Debugging Gets Assertive

The Verdi debugging system now supports assertion-based verification.

With an eye toward accommodating assertion-based verification flows, Novas Software's latest Verdi debugging platform was extended to support assertion languages and the results of assertion-based tools.

Launched last year, Verdi provides automatic analysis of cause-and-effect relationships and the ability to visualize design behavior over time. Coupling Verdi with assertions broadens the platform's debugging capabilities. Users can browse and trace assertion source code along with hardware-description-language (HDL) source and see the results of assertion evaluation annotated in the source view as well as the waveform view. It allows designers to quickly search backward in time from a value or transition to locate and isolate its cause.

Verdi's assertion language compilers initially support the OpenVera Assertions (OVA) language. Support of additional Accellera assertions is on the roadmap as standards settle out. Now available for customer beta testing, the Verdi debug platform with assertion-driven capabilities starts at $14,000 for a one-year subscription license. Verdi licensees on maintenance will be upgraded at no charge.
