Cadence Delivers Smart JasperGold Formal Verification Platform
October 4th, 2019 – Cadence Design Systems, Inc. announced the third-generation Cadence® JasperGold® Formal Verification Platform, featuring machine learning technology and core formal technology enhancements. The updates to the platform address the capacity and complexity challenges of today’s advanced SoC designs and aim to improve verification throughput.
Third-generation formal verification technology delivers an average of 2X faster proofs out of the box and 5X faster regression runs by leveraging new machine learning-enabled Smart Proof Technology. New platform also delivers more than 2X design compilation capacity and an average of 50% memory usage reduction.
The new JasperGold platform represents the latest stage of ongoing proof-solver algorithm and orchestration improvements. This latest platform incorporates Smart Proof Technology to improve verification throughput for all JasperGold apps. Machine learning is used to select and parameterize solvers to enable faster first-time proofs. Additionally, machine learning is used to optimize successive runs for regression testing, either on premises or in the cloud. With Smart Proof Technology, proofs speed up by up to 4X, and up to 6X on regression runs.
“We measured averages of 2X faster proof performance out of the box and 5X faster regression runs across our design testcases with the new smart JasperGold platform,” stated Mirella Negro Marcigaglia, Digital Design Verification Manager at STMicroelectronics. “We are also seeing non-converged properties reduced by over 50%. Combined, these improvements significantly boost our verification productivity.”
Given today’s larger and more complex SoC designs, the design compilation process sets the maximum size of design, and the compute resources necessary, to start formal analysis. The updated JasperGold platform delivers more than 2X design compilation capacity with an average of 50% reduction in memory usage during compilation, compared with one year ago. Additionally, engineers can effectively scale design capacity through advanced parallel compilation technologies that optimally use available compute resources, and by running proofs on the Cloud.
The platform’s new formal coverage technologies let engineers perform IP signoff purely within the JasperGold platform. These new formal signoff technologies include improved proof-core accuracy, new techniques to derive meaningful coverage from deep bug hunting and new formal coverage analysis views. Together those features deliver signoff-quality formal coverage metrics and enable multi-engine chip-level verification closure.
“The first-generation JasperGold platform pioneered commercial formal verification and apps in the market, and the second generation integrated Cadence technologies to establish formal verification with mainstream users,” stated Ziyad Hanna, corporate vice president, Fabric and Formal Solutions, System & Verification Group at Cadence. “Our third-generation smart JasperGold platform significantly advances core formal technology, applying machine learning to achieve tangible performance and scalability benefits for our customers.”
The JasperGold Formal Verification Platform, part of the Cadence Verification Suite, offers comprehensive coverage in the vManager™ Metric-Driven Signoff Platform, which combines JasperGold formal results with Xcelium™ simulation and Palladium® emulation metrics to speed overall verification closure. It supports the company’s System Design Enablement strategy, which enables systems and semiconductor companies to create complete, differentiated end products more efficiently. The Cadence Verification Suite is comprised of the best-in-class JasperGold, Xcelium, Palladium and Protium™ core engines, verification fabric technologies and solutions that increase design quality and throughput, fulfilling verification requirements for a wide variety of applications and vertical segments.
