Onespin Creates First SVA Solution for Gap-Free RTL Verification

OneSpin Solutions, an EDA company that provides innovative, highest-capacity formal verification solutions, announced the industry’s first verification solution that features gap-free RTL verification using SystemVerilog Assertions (SVA). This solution represents a major technical breakthrough in verification technology employing standard verification languages. It leverages a new, ground-breaking SVA Timing Diagram Assertion Library, TIDAL[tm], that helps users easily capture timing diagrams as SVA properties. Users of OneSpin’s 360 Module Verifier (360 MV) now can employ SVA to implement the GapFreeVerification[tm] process that slashes verification effort and ensures highest possible verification quality. OneSpin will demonstrate the new capabilities at the Design Automation Conference, Booth #625, June 9-12, in Anaheim, Calif.

Today’s announced innovations, combined with previously announced 360 MV support for verifying assertions and high-level properties written in SVA, make 360 MV and its GapFreeVerification process the most comprehensive formal SVA verification solution on the market. This unrivaled solution reduces verification effort up to five times compared to advanced testbenches, and enables verification of designs with more than 100K lines of RTL code – making it one of the most productive and highest-capacity formal RTL verification offerings.

GapFreeVerification is the only closed-loop verification process using SVA. It guides users in verification planning, execution, debug and formal coverage analysis. Automatic gap detection identifies unverified RTL functionality as well as gaps and errors in the specification. Thus, it greatly simplifies verification planning, and eliminates the need to construct coverage models and manually analyze extensive coverage data to assess and improve verification quality. 360 MV’s automatic gap detection also is the first technology to enable integration of verification planning, execution and verification quality analysis into a closed-loop process – the key to higher productivity and highest quality in verification.

TIDAL supports 360 MV’s intuitive operation-based verification approach. It enables users to directly transcribe timing diagrams that specify the intended behavior of module-level operations into corresponding SVA properties. Users then can employ 360 MV’s automatic gap-detection to systematically find and close all gaps in the SVA property set. TIDAL’s constructs, modeled in standard SVA, allow users to leverage the familiar concept of timing diagrams for formal verification, speeding learning and adoption by novices and formal experts.

Peter Feist, president and CEO of OneSpin, said, “Our customers requested a verification process that features automatic gap detection for SystemVerilog Assertions. We are now offering the industry’s first SVA solution for gap-free verification through a combination of our new TIDAL library and the SVA-enabled GapFreeVerification process for 360 MV. It sets unprecedented benchmarks for productivity, applicability and capacity in SVA-based formal verification, and ensures the highest possible verification quality.”

We are now offering the industry’s first SVA solution for gap-free verification through a combination of our new TIDAL library and SVA-enabled 360 MV.

Pricing and Availability
SVA-based GapFreeVerification[tm] and TIDAL[tm] are included at no extra charge in the version 5.0 release of 360 MV, available at the end of this month.
