Synopsys Delivers 2x Verification Speed-up With VCS Multicore Technology

New Technology Optimizes Verification Performance on Multicore CPUs


MOUNTAIN VIEW, Calif., April 6 /PRNewswire-FirstCall/ -- Synopsys, Inc. , a world leader in software and IP for semiconductor design and manufacturing, today unveiled new multicore technology within the VCS® functional verification solution, a key component of Synopsys' Discovery™ Verification Platform. VCS multicore technology delivers a two-times (2x) improvement in verification performance by harnessing the power of multicore CPUs. The new technology removes performance bottlenecks and speeds verification by distributing time-consuming activities across multiple cores. VCS multicore technology combines the speed-up from parallel computation with the industry-leading Native Testbench (NTB) compiler to meet the performance requirements for the verification of large-scale designs. This enhancement helps verification teams address the growing challenges of verifying increasingly complex designs and achieving first-pass silicon success.


"We continue to benefit from the innovative optimizations delivered by VCS," said Paul Tobin, director of Verification Center of Expertise at AMD. "As our engineers integrate more cores and deliver designs with an optimal balance of performance, power and virtualization, our verification teams rely on the speed-up delivered by VCS multicore to quickly verify these complex designs on Quad-Core AMD Opteron processors in our server farm."


Application and Design Parallelism

SystemVerilog adoption increased the deployment of advanced technologies such as constrained-random testbenches, assertions and coverage. Synopsys pioneered NTB optimization and delivered 5x faster performance on single-core CPUs by natively compiling these technologies. With the new multicore technology, the VCS solution extends the NTB optimization to run on multicore CPUs and parallelizes the entire verification environment to maximize performance. This includes the design under test as well as verification applications such as testbench, assertion, coverage and debug. Design-level parallelism (DLP) allows a user to concurrently simulate multiple instances of a core, several partitions of a large design, or a combination of the two. Application-level parallelism (ALP) allows users to run testbenches, assertions, coverage and debugging concurrently on multiple cores. The combination of DLP and ALP optimizes VCS performance over multicore CPUs.


"Synopsys continues to develop and deliver innovative optimizations to push the performance curve," said Manoj Gandhi, senior vice president and general manager, Verification Group, Synopsys. "VCS multicore technology builds on the already successful Roadrunner, Radiant and Native Testbench optimization and addresses the rapidly growing demands of modern verification. The new technology creates a foundation on which Synopsys will deliver even more innovations for multicore computing platforms."



The multicore technology in the VCS functional verification solution is available now in Beta and is expected to be in production in calendar Q3 of 2009.
