Open Verification Library (OVL) Technical Subcommittee

Accellera OVL V2.4 now available for download


Accellera's OVL Survey

Help us improve the Open Verification Library (OVL) to achieve an even better Assertion-Based Verification (ABV) industry standard. The Accellera OVL technical committee is interested in learning about your usage of assertion checkers and suggestions for future enhancements of OVL. If you do not currently use OVL, we want to learn what barriers exist that prevent you from adopting OVL.

Please take a few minutes to participate in our survey. Your opinion is very valuable to us!

Scope and charter

The OVL library of assertion checkers is intended to be used by design, integration, and verification engineers to check for good/bad behavior in simulation, emulation, and formal verification.

The subcommittee is responsible for the definition and development of the standard Open Verification Library (OVL) language reference manual and assertion-checker libraries.
