Cologne, 11/02/2019 – information Aktuell .- The Cologne-primarily based IoT provider 1NCE GmbH has offered more than a million SIM playing cards given that market launch 5 months in the past. the key behind the success: through offering an IoT flat rate, the know-how company presents mobile verbal exchange between contraptions on the web of things (IoT) at a tons-vital inexpensive price aspect in comparison to most different providers global, at the same time as still guaranteeing the highest quality provider. The technology – which is already obtainable in more than 30 international locations – was developed by 1NCE completely for IoT functions. With its robust center of attention, the enterprise naturally distinguishes itself from significant community operators. "As a really good IoT network service, we are growing a new industry average with a purpose to allow significant boom within the internet of things and computer-to-machine communication for the first time," pointed out Alexander P. Sator, CEO of 1NCE
software eventualities exist already in big numbers, however the implementation of clever IoT techniques frequently fails because of the complexity and value of establishing instant community connections. here's the place 1NCE is available in with a modern reasonably-priced-charge, splendid solution this is optimal, peculiarly for lengthy-lasting B2B purposes: The “1NCE in a Lifetime”-IoT flat rate comprises a data quantity of 500 megabytes and 250 SMS at a value of most effective 10 euros for 10 years, with no different hidden expenses. "here's excess of is required for the change of primary tips in IoT purposes devoid of speech," emphasised Younes Allaki, CTO at 1NCE. "should the facts extent nonetheless not be satisfactory for a ten-yr duration, valued clientele can exact-up their originally booked extent at any time and will nonetheless stay a long way beneath the regular charges." In distinction to classic fashions with monthly expenses, 1NCE ensures highest expense transparency with its pre-paid all-inclusive providing that makes IoT connectivity calculable and good value for both birth-u.s.or colossal organisations. The 1NCE offering is even more compelling considering it comes with developed-in scalability as well as high availability and safety.
Supported with the aid of Deutsche Telekom AG, 1NCE utilizes the mobile networks of all essential European community operators for its IoT radio features and is additionally available in China, Russia and in the us of a. The carrier is continually supported via at the least two – rather frequently even via all – network operators in a rustic in order to guarantee highest availability. an additional attribute that makes the know-how entertaining is the capacity to seamlessly swap between the diverse cellular communications necessities 2G, 3G, 4G or NB-IoT. "when you consider that our SIM card has entry to all available networks and helps all average cellular communications specifications, we be certain funding safety and future viability," defined Sator.
The addressable market is big: experts from the GSM association (GSMA), the global business affiliation of GSM cell phone suppliers, estimate the volume at 25 billion instant contraptions via 2025. Many industries have a superb want for connectivity: logistics carrier providers ought to locate their containers, energy providers are looking to handle measuring instruments directly, car fleets should be stronger coordinated, assurance agencies need to install telematics capabilities. in more precise instances this ability that in smart metering eventualities, electricity, gas and water meters file the meter studying to the utilities themselves. in the wise metropolis, streetlight luminaires signal after they deserve to be replaced. The waste container itself stories that it wants emptying, and in industrial creation, wear components akin to drills can initiate their replacement instantly. "quickly every product developed will include radio-potential and as a consequence be able to communicate," endured Sator.
1NCE GmbH changed into founded in January 2017 and started revenue in August 2018. today, the enterprise has greater than 50 personnel.
1NCE is the first wholly-fledged IoT community carrier on the planet to offer speedy, comfy and respectable connectivity capabilities at within your means based on an IoT flat rate. This makes IoT applications comparable to tank maintenance, wise metering or car telematics most economical. The "1NCE in a Lifetime fee" includes 500 MB data volume, 250 SMS and free access to the 1NCE Connectivity administration Platform via cyber web and API. To provide the provider, 1NCE cooperates with Deutsche Telekom AG and leading telecommunications providers and supports all normal mobile communications specifications (2G, 3G, 4G, NB-IoT). The enterprise headquartered in Cologne offers its flat fee very nearly world-broad. 1NCE GmbH changed into headquartered in 2017 together with Deutsche Telekom AG and has greater than 50 team of workers in Cologne, Hamburg, London, Rome, Paris and Riga.

these days Microsoft has introduced support for the OpenAPI specification v3 in Azure API management, which is their provider that makes it possible for the install, publishing, monitoring and maintainence of APIs. support of the OpenAPI specification has been implemented throughout the OpenAPI.web SDK and allows the abstraction of the definition of APIs from their implementation.
The OpenAPI specification, in the past referred to as Swagger, gives the capacity to explain RESTful web functions in a language independent way. As OpenAPI is widely adopted, a diverse ecosystem is available with tools for designing, documenting, building, checking out and enforcing governance. The specification gets overseen by using the OpenAPI Initiative, owned via the Linux foundation, and has a wide variety of organizations driving its building, together with companies corresponding to SmartBear, Microsoft, and WSO2. anyone can observe or even make a contribution to the building of the specification on the GitHub repository of the OpenAPI Initiative.
based on Tom Kerkhove, Microsoft Azure MVP and Azure Architect, the specification has a crucial position when exposing APIs to their buyers.
presenting clear and neatly-documented APIs is a must. This allows your patrons to grasp what capabilities you supply, what they're for and what to are expecting. here is where the OpenAPI specification, aka Swagger, is available in and defines how APIs may still be defined across the business, in spite of what technology is below it.
edition three of the specification has introduced several adjustments, and as such these are now additionally obtainable for Azure API management. for example, this new edition brought a whole new structure with accessories comparable to headers, hyperlinks, and callbacks, taking a extra modular approach within the definition, as described by way of guy Levin, CTO at RestCase.
version 3.0 of the API specification layout has taken a much extra modular, and reusable method to defining the surface enviornment of an API, enabling greater vigor and flexibility when it comes to describing the request and response models, in addition to offering particulars on the common components that make up API utilization just like the underlying information schema and safety definitions.
another brought option is to include callbacks to an operation, that means it's now possible to explain webhooks for these. at last, linking enables defining relationships between diverse paths of the APIs, presenting the potential to extend on its attributes.
photograph supply: https://weblog.restcase.com/6-most-huge-adjustments-in-oas-three-0/
Following the announcement, it's now viable to import OpenAPI v3 definitions in Azure API administration, albeit with some restrictions. currently, here's feasible throughout the portal or by the use of the relaxation API. consequently, capabilities for exporting the OpenAPI descriptions are also obtainable, either in the developer portal or using an additional call to the leisure API.
at last, earlier than these capabilities will circulation into general availability, and it will additionally turn into viable to make use of the PowerShell SDK for doing each import and export of the definitions.
MOUNTAIN VIEW, Calif.--(company WIRE)--Veritas technologies, the leader in information management, these days introduced the results of a worldwide survey indicating that virtually three-quarters of organisations continue to undertake multiple inner most and public cloud innovations. The findings spotlight the want for corporations to adopt strong tips management and protection strategies.
The analyze, commissioned by way of Veritas and carried out through Cicero neighborhood, surveyed 1,800 global IT determination makers in agencies with as a minimum 500+ personnel and at the least 75TB of records under administration. ordinary, the research published that enterprise-critical workloads within the public cloud are set to double within the subsequent 24 months – roughly the same price as non-essential workloads – placing force on IT departments to make certain their whole enterprise features, now not just their infrastructure, are totally attainable and secure.
The analyze examined each the expense at which corporations are moving facts to the cloud, using each deepest and public cloud capabilities, as well because the reasoning in the back of their selections. The research also looks to disprove some standard perceptions about cloud adoption. for example, one typical view is that much less critical workloads will migrate to the public cloud first and at a quicker price. whereas this can also were the case early on, the analyze found that here is transferring: enterprise-important workloads together with CRM and ERP are moving to the cloud on the equal charges statistically – from 25-30% -- as different, less critical workloads. while these findings point out an improved have faith in moving statistics of all kinds to the cloud, it also translates to introduced power for service suppliers to ensure high availability and evade downtime, as well as challenges IT departments to have the right facts insurance policy concepts in region that can span heterogeneous infrastructure – on and off premise.
Key findings of the look at consist of here:
“This research underlines the present state of the hybrid cloud world,” observed Simon Jelley, Veritas VP of Product administration, Veritas technologies. “This world is extra – no longer much less – heterogeneous, that may imply increasing complexity from an advice management perspective. businesses ought to be extra vigilant than ever in opting for IT blind spots and advantage safety hazards to stay away from unplanned downtime or an guidance crisis.”

This chapter, from Upgrading and Repairing Networks, 5e, looks at the network's logical and physical design to assist your planning when creating a new network.This chapter is from the book
Many types of networks were discussed in Chapter 1, "A Short History of Computer Networking," from ARPANET to TCP/IP. And in Chapter 2, "Overview of Network Topologies," you learned about the various topologies you can employ when designing and creating a local area network (LAN), and we also looked at some scenarios in which several networks were connected to form a wide area network (WAN). In this chapter, we will look at another aspect of creating a network: the network's logical and physical design. The physical aspects of your LAN will depend on the underlying physical transport technology—Ethernet or Token-Ring, for example, or possibly ATM, which is supported as a LAN protocol in products such as Windows 2000/XP, Windows Server 2003, and Linux. Depending on which technology you use, there will be one or more LAN topologies from which to choose.
Before you can begin to design a physical network, however, you first must determine your needs. What services must you provide to your user community? What are the resources you'll need? If you have to compromise, what will it take to satisfy the most users or to provide the more important services? You then will have to take into account network protocols, applications, network speed, and, most important, network security issues; each of these figures into a network's logical design. Another important factor your management will probably force you to consider is cost—you can't forget the budget. These factors make up the logical design for your network. You first should decide what you need and what it will take to provide for those needs.
If you are creating a new network and purchasing new applications, you will probably spend most of your time considering the licensing and other financial costs (training users, network personnel, and so on). If you are upgrading older applications, several other factors come into consideration. Many applications that were coded using COBOL, BASIC, FORTRAN, and other languages that helped jumpstart the computer age may have built-in network functionality based on older proprietary network protocols. If this is the case with your network, you have to consider several things. What will it cost to update thousands of lines of code (or more) to more modern versions of the same programming language? What will it cost to upgrade these programs to newer object-oriented languages? To save money, can you upgrade part of your network and use gateway hardware/software to connect to older network components?
Because of the costs associated with coding applications that were created many years ago, and the expenses that will be required to update them to modern programming languages, you may be forced to maintain legacy applications for a few years while replacement applications are designed and created. You may find a packaged application that can be used to replace older programs. This problem will apply mostly to proprietary computer architectures, instead of Windows or Unix platforms. If you can simply make minor changes and compile the source code so that it will run on a newer operating system, your costs will be much less than if you have to re-create the applications your users need from scratch. Another cost associated with upgrading to new programs is training users and help-desk personnel.
When you plan a logical network design, you can start from one of two places. You can design and install a new network from scratch, or you can upgrade an existing network. Either way, you should gather information about several important factors before you begin the logical design. For example, depending on the services that will be provided to clients, you might need to analyze the possible traffic patterns that might result from your plan. Locate potential bottlenecks and, where possible, alleviate them by providing multiple paths to resources or by putting up servers that provide replicas of important data so that load balancing can be provided. The following are other factors to consider:
This seems like a very simple question. However, I'm not saying, "What are your clients' names and how well do you know their children?" I am referring instead to your knowledge of the job descriptions for the users on the network. You need to assess work patterns for various departments so that you can appropriately place servers, high-bandwidth links, and other such things in the appropriate physical location of the network. If most of the network traffic you expect to see will come from the engineering department, you'll need to provide that department with a large data pipe. In Chapter 4, "Upgrading Strategies and Project Management," you'll find more information about surveying the user community to come up with a plan that places resources where they are needed.What Kinds of Services or Applications Will the Network Offer?
Of course, everyone knows that the most important function of a network today is to support multiuser gaming. Seriously, though, you need to make a list of the kinds of applications currently in use, as well as a list of those requested by users. Each application should have a written risk assessment document that points out potential security problems, if any. Typical network applications today include FTP, telnet, and, of course, browsing the Web. There are "secure" versions of these applications and there are versions that leave a door wide open into your network. Whatever list of applications you chose to support over the network, keep in mind two things:
A commonly overlooked method for getting data files out of a network and onto the Internet is to simply send the files as an attachment to an email. So if you think you've blocked file transfers by disabling FTP access through the firewall, this example should show that you really do need to do a thorough evaluation of any new application or service you will allow on the network. New applications should be justified with facts that show why they are needed. If an existing application can be used to accomplish the same goal, why do you need another application? Should you retire the older application and use a newer one? Pay attention to the details. And don't forget to test new applications to ensure that they perform as expected. The same goes for older applications—will they work on the new or upgraded network?
Lastly, do you monitor network usage? Do you want to permit users to spend their days browsing the Net, or checking personal email while at work? Many companies have policies that apply to using the telephone for personal business. Do you overlook this situation when giving users email capability? Are you preventing access to sites that are obviously not business-related?What Degree of Reliability Do I Require for Each Network Link?
Just how much downtime is acceptable? For most users, the answer would be zero. Important components of your network, such as file servers, should have fault tolerance built in from the bottom up. In large servers, you'll find dual-redundant power supplies (each connected to a separate UPS), and disk arrays set up using RAID techniques to provide for data integrity in the event that a disk goes south. If a link between two offices needs to be up 100% of the time, you should plan for multiple links between the two sites to provide a backup capability. In this case, you also can justify the cost of the extra link by using load balancing so that network response time is improved. And, if you are using multiple links to remote sites, it's always a good idea to have more than a single path to the site. At one site this author worked at, there were redundant power lines bringing electricity into the site—side-by-side. If a tree falls, will it bring down one or both of those power lines?
Another technology that can be used to provide an extra layer of redundancy, as well as high-speed access to storage devices, is the Storage Area Network (SAN). A SAN is a network that is separate from the LAN and contains only storage devices and servers that need to access those devices. Because the network bandwidth is not shared with LAN users, multiple servers can access the same storage. If one server fails, other servers can be configured to provide redundant access to the data. Also, the same RAID and other redundancy techniques used for storage devices that are directly attached to a server (such as the SCSI hardware and protocols) can be used on a SAN.
The terms RAID and UPS are important in today's networks, as is the concept of load balancing and dual-redundant power supplies in large networks. You can find out more about RAID (Redundant Array Of Independent Disks) and UPSs (uninterruptible power supplies) by reading Chapter 5, "Protecting the Network: Preventative Maintenance Techniques." For more information about SANs, see Chapter 11.
The old saying "If it ain't broke, don't fix it" doesn't apply to networks. You should always be proactively looking for potential single points of failure and doing something to fix them. By building redundancy into the network design at the start, you'll save yourself a lot of grief in the future.
Chapter 5 can give you more suggestions about using clustering, backups, uninterruptible power supplies, and other techniques that can keep the network up and running.Choosing a LAN Protocol
Today the de facto protocol of choice has to be TCP/IP. However, other protocols have their place in some vertical markets. In this book, we talk about NetWare. NetWare has been around so long that you might find you have no choice when designing an upgrade but to keep using IPX/SPX, depending on the applications your network uses. However, even NetWare has moved toward using TCP/IP as the underlying protocol. This is basically the case for version 5.x and 6.x of NetWare. Older NetWare networks should upgrade, if possible, to one of these newer versions. If you will be connecting the network to the Internet, TCP/IP will be a necessity. Even if you don't expect to have an Internet connection, you'll find that choosing TCP/IP is a more practical choice today because most applications work with it and there is a large market of trained professionals who can be hired to manage a network built on TCP/IP. NetWare 6.x provides backward compatibility with IPX/SPX for the most part, but newer features such as the iPrint—which uses the Internet Printing Protocol—require TCP/IP.
In addition to transport protocols such as TCP/IP and IPX/SPX, you must consider application protocols that can be used on the network. For example, to simplify administering configuration information for a large number of computers, you might want to use the Dynamic Host Configuration Protocol (DHCP), which is discussed in Chapter 28, "BOOTP and Dynamic Host Configuration Protocol (DHCP)." If you want to provide a central name resolution service, you might choose the Domain Name Service (DNS), which is covered in Chapter 29, "Network Name Resolution." If you are going to operate a Windows network that has pre–Windows 2000/XP clients, you might need to use the Windows Internet Naming Service (WINS) for backward compatibility.
So when thinking about a network protocol, remember that it's not just one protocol you need to worry about. After you've decided which protocols are necessary, research the security implications of each.It's Virtually Universal: TCP/IP
For all practical purposes, the standard LAN protocol today is TCP/IP. This is partly due to the rapid growth of the Internet, and the necessity of most businesses of having a Web presence, as well as the large number of vendors that have adopted this protocol suite. If your LAN is still using an older proprietary network protocol, you should seriously consider what it would take to upgrade to TCP/IP. Currently, TCP/IP version 4 is the most widely used protocol. In the future you can expect that the next version (IPv6) will start to find its way from the core of the Internet out to the edge, where your network resides. While technologies such as Network Address Translation (NAT) are widely employed to remedy the problem associated with the limited address space provided by IPv4, IPv6 will enable a much larger address space. Combine that with Network Address Translation, and the long-term bets are going to be on IPv6, or possibly some of the features that are part of IPv6. In addition to giving you a larger address space, IPv6 includes other important features. Those that will affect your network the most are security mechanisms, which will only become more important as Internet commerce continues to grow.
For a detailed introduction to TCP/IP, see Chapter 24, "Overview of the TCP/IP Protocol Suite"; Chapter 25, "Basic TCP/IP Services and Applications"; and Chapter 27, "Troubleshooting Tools for TCP/IP Networks."
There is one very important reason you should consider TCP/IP as a LAN protocol: There are more trained professionals knowledgeable in TCP/IP than any other LAN protocol at this time. It is interesting to note that in Windows NT 3.51, the default network protocol was Microsoft's implementation of IPX/SPX (NWLink). In Windows NT 4.0 (and successive operating systems, from Windows 2000, XP, and Server 2003), the default network protocol is TCP/IP.
If your network is composed of several operating systems, from Windows to NetWare to Unix and Linux, then the bottom line is that TCP/IP is the lowest common denominator that will allow the easiest connectivity and interaction between all of these. Even Microsoft's now-legacy NetBIOS/NetBEUI protocols have been adapted to run over TCP/IP.Novell's NetWare Version 6.5
NetWare was perhaps the first attempt at seriously providing a LAN protocol that was easy to use. The basic file and print services offered by early versions of NetWare were much better than other solutions available at that time. After it became established in the business community, NetWare became the network solution of choice in many business environments that used the PC. Microsoft countered this success with its LANManager products, which were also marketed by other vendors in their own way, such as the Pathworks solution from Digital Equipment Corporation.
Today NetWare is a totally revamped solution to LAN connectivity. It provides many new features that are addressed to specifically make use of the Internet, and allow mobile users to connect to their home networks, as well as to enable NetWare users to make connections to outside networks. For example, the iPrint feature enables NetWare users to print to a printer on a remote network. For example, instead of sending a catalog that may be out of date in a month or so, you can use iPrint to periodically send specific information relevant to each customer, by printing it directly to the customer's printer.
And NetWare's iFolder allows mobile users to synchronize data stored on remote computers (such as a laptop computer) with the data stored on the company's network. Microsoft and other vendors offer similar features. However, the point to remember is that if you already are a NetWare user, you don't have to throw out your existing investment and move to a Microsoft network, or even a Unix/Linux environment. NetWare has changed as the market has changed, and you might find it less expensive to upgrade to NetWare 6.5 than to migrate to another platform. The bottom line involves not just the cost of migrating to another operating system, but the costs involved with retraining your network administrative personnel in new technology.
Because NetWare 6.5 is so tightly integrated with the IP protocol, and also offers backward compatibility with IPX/SPX, admins for existing NetWare networks should consider upgrading to NetWare 6.5 as well as considering other options.
If you want to move to Linux, Novell makes it easy by incorporating an enhanced version of NetWare 6.5 and SuSE Linux into its Novell Open Enterprise Server. Open Enterprise Server supports both Linux and NetWare-specific software and features, enabling you to move to Linux gradually.Other LAN/WAN Protocols
The distinction between LAN and WAN (wide area networking) protocols is beginning to blur. Ethernet was once considered to be a LAN protocol. As time has passed, other technologies, such as Token-Ring, have become minor players in the LAN world. Yet the opposite is true of Ethernet. It has grown from a modest specification endorsed by Intel, DEC, and other vendors, such that it now can be considered a WAN protocol. The capabilities introduced by current LAN technologies are beginning to erode the differences between a LAN and a MAN (metropolitan area network). When the fourth edition of this book was published, Gigabit Ethernet was starting to fall into the inexpensive range of network topologies. That trend has continued and now 10Gigabit Ethernet (10GbE) is frequently being used in enterprise data centers. Today you may be using 100BASE-T for connecting client computers to the network, and Gigabit Ethernet to connect network segments via the network backbone. In some cases your network might even be exclusively based on 10GbE.
What does this mean to a network administrator today? With 10Gigabit Ethernet, you can use TCP/IP not only to create a local area network backbone, but to extend that reach to a metropolitan area network. And because TCP/IP is so intertwined with Ethernet, you can achieve an end-to-end MAN link that uses TCP/IP over faster Ethernet connections. Instead of employing more expensive solutions, such as SONET, you can now connect branch offices in the same geographical area using just TCP/IP.
You may not have to worry about installing expensive equipment used by SONET and other typical MAN protocols. Still, for the long haul—for example, between different cities—other protocols such as ATM and Frame Relay will come into play.
For more information about SONET, ATM, and Frame Relay, see Chapter 15, "Dedicated Connections."
Conformal 4.0 includes enhancements to Conformal Logic Equivalence Checker (LEC) and integrates new Conformal family products, making Verplex the only equivalence checking company delivering a complete solution for SoC verification.
Equivalence checking has become a standard component in an application specific integrated circuit (ASIC) design flow. Formal techniques used by equivalence checkers have proven to be the best technology to exhaustively check for errors introduced by design implementation tools or manual engineering change orders (ECOs).
Traditionally, equivalence checkers have forced designers to "black box" much of their SoC, including memories, complex I/O pads, custom logic and advanced datapath. By black boxing these components, equivalence checkers only verified random logic modules, leaving the most complex and error-prone areas of the design unverified.
Conformal 4.0 addresses these limitations found in graphics, multi-media, digital signal processing (DSP) and communications designs, which often require advanced logic, datapath, memories and custom design modules.
"Verplex continues to deliver breakthrough technology and we are the first to offer a comprehensive equivalence checking solution that enables designers to verify the complete SoC," says Michael Chang, Verplex president and chief executive officer (CEO). "Formally verifying the complete SoC with our best-in-class products enables our customers to exhaustively verify the most complex portions of their designs."
Conformal 4.0 Details
Designs have grown so complex that an independent verification, such as Conformal 4.0, is needed to audit the process by which circuitry is generated to ensure correct results. Other formal verification tools are not independent, and may require "side files," or data clandestinely passed from implementation tools to verify these circuits. This increases the risk that formal verification uses the same assumptions made during the implementation process, causing it to miss bugs introduced by implementation tools.
Verplex's Conformal 4.0 product family continues to provide best-in-class performance and usability for the entire design flow from register transfer level (RTL) to layout. It includes five products designed to address the SoC verification challenge: Conformal LEC; Conformal Datapath (DP); Conformal Logic Transistor Extractor (LTX); Conformal Memory (MEM); and Conformal Layout Versus RTL (LVR). All operate within the same user interface, were designed for ease of use and share similar debugging approaches.
Conformal 4.0 enhances Verplex's flagship product -- Conformal LEC -- which performs RTL-to-gate and gate-to-gate equivalence checking. Among the enhancements are improvements in performance, ease of use, Verilog 2001 support, hierarchical comparison, design mapping and the Verplex schematic viewer.
To address the increases in design size and complexity, Verplex continues to improve performance and memory utilization within Conformal LEC. Users will benefit from up to 10x performance improvement for gate-to-gate comparisons and up to 5x performance improvement for RTL-to-gate comparisons. Memory utilization was also improved and users will benefit from up to 30 percent less memory consumption.
Conformal LEC includes numerous ease-of-use enhancements, including a schematic viewer, value annotation on the source code browser for error diagnosis, on-the-fly ECO editing for design validation, and automatic multiplier analysis.
The Verplex schematic viewer improves performance by using a tightly integrated environment. This integration enables users to display unlimited schematic sessions with a single license and includes formal verification specific functions such as interactive prove and automatic pruning of non-controlling logic.
Source code value annotation and tracing further improves error diagnosis by displaying error patterns on the source code and enabling the user to identify the source of the error by tracing drivers and loads. Expanded what-if capability enables the user to modify the design and validate the modification without leaving the Conformal environment, saving hours in debug and iteration time.
With this release, Conformal LEC expands its language support to include support for Verilog 2001. This enables more efficient capture of design RTL with constructs such as multi-dimensional arrays, signed arithmetic extensions, 'generate' statement, combinational logic sensitivity, and re-entrant tasks and functions. Conformal LEC provides the most complete support for Verilog 2001 features used within major synthesis and simulation tools.
Hierarchical comparison and design mapping were also enhanced within Conformal LEC. Hierarchical comparison is often recommended for large designs to reduce run times and improve debug when design errors are found. Capabilities were improved to include enhanced module boundary constraint generation and intelligent module flattening.
Conformal LEC further improves its mapping capabilities to address common naming conventions used within implementation tools and to improve designer efficiency in completing this step in the process. The design-mapping step of the equivalence checking process aligns verification points between two designs being compared and these points must be consistent to achieve successful verification.
Conformal Datapath (DP)
Conformal 4.0 integrates recently announced Conformal DP to address requirements of high-performance SoC designs such as applications in graphics, multimedia, DSP, and communications that often use advanced datapath optimizations.
Formally verifying advanced datapath has traditionally been a challenge for equivalence checking. Verplex has introduced technology capable of verifying a wide variety of datapath structures. Designers are now able to automatically verify flat datapath modules, complex merged operators, advanced pipelining techniques, and carrysave architectures.
Conformal Logic Transistor Extractor (LTX)
SoC designs frequently include custom I/O cells and designers are leveraging custom design techniques to meet performance requirements. Conformal 4.0 integrates Conformal LTX into its environment and has added improved transistor schematic and analysis capabilities that improve the users' ability to efficiently compare designs.
Conformal LTX automatically abstracts gate-level models from transistor-level circuits. This enables formal verification between the RTL model used for design simulation and the actual transistor circuit integrated prior to tapeout. It ensures that the system verification performed throughout the entire design process is valid by proving the consistency between the simulation model and actual circuit. The abstracted models may also be used within other applications, including automatic test pattern generation (ATPG), simulation acceleration or emulation.
Conformal Memory (MEM)
Memory typically occupies more than half of the die area on SoC designs and trends indicate that embedded memory content is increasing in terms of size and complexity. Historical memory verification methods involved the use of simulation with all of its drawbacks such as challenging debug, degraded quality of verification, and increased risk of expensive silicon re-spins due to missed bugs. The simulation approach is also time consuming, particularly at the transistor or SPICE level where memories are designed. Additionally, the simulation approach is incomplete, proving that designs are free from functional errors under only tested conditions, risking that bugs will slip past to final silicon.
Verplex's Conformal MEM offers an exhaustive verification solution that addresses deficiencies of traditional approaches to memory verification. Through the use of equivalence checking, 100 percent exhaustive coverage and fast system-level verification are achieved.
Conformal Layout Versus RTL (LVR)
Conformal LVR further expands traditional equivalence checking to enable verification of the final layout. Previously, equivalence checking verified designs through the final gate-level netlist, which created a verification hole by not ensuring that the final SPICE netlist was consistent with the golden RTL. Conformal LVR enables formal verification of the final SPICE netlist against the golden RTL or final gate-level netlist to ensure that the design taped out is functionally equivalent with golden RTL and the final gate-level netlist.
Pricing and Availability
The entire Conformal product family is available now. U.S. price for a three-year, time-based license for Conformal LEC is priced from $57,600. Additional packages are available for the complete Conformal product family, which is supported on Hewlett Packard HP-Unix(TM), Sun Microsystems Solaris(TM), IBM AIX(TM), and Linux operating systems platforms.
