OneSpin Solutions Enhances 360 MV for Safe, Exhaustive 4-State X-Analysis and X-Verification

New 4-State Formal Analysis and Verification Capability Ensures Absence of X-Related Design Errors and RTL-to-Netlist Mismatches Design Automation Conference 2010

MUNICH & SUNNYVALE, Calif.-- June 7, 2010--OneSpin Solutions, an EDA company that provides innovative formal assertion-based verification solutions, today announced that it has enhanced its flagship product 360 MV to perform 4-state X-analysis and X-verification. This enhancement enables safe, exhaustive analysis of unknown, undefined, and “don’t care” signal values (X’s) and their propagation through a design. In contrast to simulation, it enables users to safely uncover all locations and conditions of unintended, dangerous X-propagation that lead to data corruption or errors in control paths. Moreover, 360 MV’s 4-state analysis does not suffer from the X-optimism that plagues 4-state RTL simulation, which results in incorrect coverage information, potential masking of design bugs and mismatches between RTL and netlist simulation – sources of functional errors that are often extremely challenging and time-consuming to find. OneSpin will show 360 MV’s 4-state formal analysis for the first time in public at a free verification tutorial in Booth #1311 at the Design Automation Conference (DAC) in Anaheim, Calif., June 13-18, 2010. “For example, designers can now easily determine whether given registers can safely be left uninitialized – to reduce chip area – without breaking their design. 360 MV ensures the X-robustness of designs before synthesis, saving effort in late gate-level simulation.”

.360 MV’s support of 4-state logic extends the 2-state logic (0,1) commonly used in formal analysis to include X and Z (floating values). 360 MV automatically identifies all design signals that can become X, and enables designers to use X-aware constructs – such as “$isunknown” and “===” – to write simple assertions to fully explore the propagation of X’s through their design. Failing assertions are debugged using 360 MV’s RootCauseAnalyzer environment. Its waveform viewer, SVA debugger, fan-in viewer, RTL value annotation, and driver tracing afford full visibility of X’s and full traceability of X propagation in the design, unlike 2-state formal analysis.

“360 MV allows users to fully exploit the use of X’s for RTL verification and synthesis optimization without the pitfalls and risks of X-related bugs,” Michael Siegel, OneSpin’s VP Product Marketing, explained. “For example, designers can now easily determine whether given registers can safely be left uninitialized – to reduce chip area – without breaking their design. 360 MV ensures the X-robustness of designs before synthesis, saving effort in late gate-level simulation.”

The new enhancement is available now in OneSpin’s 360 MV.

OneSpin at DAC 2010

OneSpin will exhibit 360 MV in Booth #1311 at DAC 2010 in Anaheim, Calif., June 13-18. Besides the complimentary 4-state formal analysis tutorial, three additional complimentary assertion-based verification tutorials will show engineers (1) the use of formal coverage analysis to automatically detect verification holes, (2) gap-free processor verification, and (3) progress in the exhaustive verification of complex arithmetic. OneSpin will show these tutorials each hour. Contact info@onespin-solutions.com for more information and to schedule private meetings at DAC.
