5/31/2005 - TransEDA, the leader in Coverage and Verification Measurement solutions for electronic designs, announces the launch of AssertainTM, the first independent Verification Closure Management (VCM) tool that delivers, in a single environment, total measurement and control of the digital design verification process.
Covering all front-end design stages from original text specification through to validated RTL, AssertainTM monitors, measures and manages the verification process in one integrated environment. The tool seamlessly brings together rule, protocol and assertion checking; code and assertion coverage; design and assertion coverability analysis; test grading and optimization, linked to specification coverage using proven requirements traceability techniques.
Verification Closure Management
Verification Closure is achieved when a pre-defined level of confidence in the correctness of a design has been attained. Such confidence comes when the design team can prove that all design requirements has been implemented and verified.
Increasing circuits’ complexity, time-to-market, corner-case bugs - and more - all conspire to compound the verification problem. Project managers are forced to make a trade off between the level of verification achieved, time-to-market, and the risk of taping out a non-functional chip.
To overcome these issues, engineering teams had to multiply their verification resources and augment the verification time in an attempt to decrease the risk of an expensive re-spin. The main reason for this inefficiency is the lack of unified and accurate measures of verification quality and completeness.
TransEDA enhances control of the verification process
AssertainTM has been built around a revolutionary assertion coverage technology. Deploying comprehensive and unique assertion coverage metrics such as structural, step and variable coverage, TransEDA’s solution enables precise measurements of how well assertions have been exercised by simulation, and how well they cover the intended behavior.
The cross-linked results from assertion coverage and code coverage are combined in a single, unified database that provides a clear view of how design verification is progressing.
Seamless mix of static and dynamic technologies
In addition to recording code and assertion coverage from dynamic simulation, TransEDA has embedded in AssertainTM its customer-proven formal engine, to be used transparently where formal algorithms are best suited to address a verification problem.
This engine augments the capabilities of the tool’s integrated rule checking with advanced formal verification of design consistency rules, such as bus contention and high impedance, FSM deadlock and livelock, array out-of-bound, etc. Formal technology is also used to automatically check protocol coverage and compliance with bus standards such as OCP, AHB and AXI.
Empowered by Coverability Analysis, and linked to initial specifications
Assertions which are not fully coverable not only slow down simulation, but may also appear to pass only because they are not reachable, thus giving engineers a false sense of security and increasing the risk of an re-spin.
TransEDA has integrated its unequaled Coverability Analysis technology into AssertainTM. Design Coverability Analysis can shave weeks off the verification time by applying formal techniques to identify areas where additional testing should be directed, filtering out those that are not reachable.
Assertion Coverability Analysis similarly provides an accurate measure of the effectiveness of PSL or SystemVerilog Assertions in a design.
However, verifying that the product is being built right is useless if one does not ensure that the right product is being built. AssertainTM provides a unique solution linking specification requirements, RTL, assertions and tests, to give engineers the ability to automatically track and verify that all original design requirements have been met and properly tested, therefore providing, for the first time, a specification coverage metric closely linking the specification, the RTL and test-benches via assertions.
An open and independent solution
Independent of platforms, languages, EDA vendor or verification tools, AssertainTM provides a single data point for the Assertion-Based Verification (ABV) approach.
GUI or command line interfaces combined with interactive or batch mode operations enable the tool to easily fit into any existing design flow. TransEDA users enjoy full backwards compatibility with existing TransEDA tools and results files allowing a smooth and seamless up-grade path.
The Logical Step to Verification Closure
For long, users have had to use a collection of separate verification tools, such as simulation, emulation, acceleration, pseudo-random testbench generation and formal verification. However, despite the current trend to integrate these point tools in platforms, they are still not working smoothly together, mainly due to the lack of common metrics to measure what these technologies really verify.
AssertainTM, TransEDA’s new generation product represents a major advance in delivering a coherent and integrated verification closure solution. The results from specification coverage, assertion coverage, advanced code coverage, and coverability analysis are combined in a single, unified set of metrics and cross-linked together to provide a complete audit of your design as you progress towards a successful and faster tape-out. TransEDA is the only company to offer an open and independent solution for Verification Closure Management.
Pricing and Availability
AssertainTM is available on Solaris and Linux. Pricing starts from $30K for a perpetual license.
TransEDA will demonstrate this innovative new approach to design verification at the 42nd DAC (Design Automation Conference) June 13 – 17, 2005, in San Diego, CA.
