Hailo successful static sign-off for edge AI processor using Real Intent Meridian CDC & Ascent Lint. Includes: Ascent Lint shortened their verification time an estimated five weeks by reducing simulation debug. Additionally, Hailo was able to get good quality results from Meridian CDC within the first two weeks. Also, the ease of integration of IP vendor constraints avoided noise in CDC runs.

Meridian RDC‘s engine is specifically customized for RDC.  This makes Meridian RDCs reports much simpler to go through.  9x fewer false violations [vs. a competitor’s RDC tool] make for a more efficient debug process for us.

“The Meridian RDC runtime was 3x to 4x faster than the [competitor’s RDC tool] runtime for the same design.”

Palo Alto Networks

This case study covers the advanced X-propagation methodology that Palo Alto Networks developed to identify X-initialization source errors and fix them to prevent the error from propagating.

Results include Meridian RXV’s runtime performance, plus an X-propagation bug Meridian RXV caught which was missed by simulation.

Western Digital developed an enhanced clock & reset verification methodology to make the Meridian CDC static sign-off tool aware of Western Digital’s clock and reset architectures. The results were: 1) They exponentially reduced their CDC sign-off noise and debug effort, and 2) They caught corner-case reset synchronization issues because only real violations were flagged with the enhanced methodology.
