Welcome to the OVL Users Site
This website provides resources for users of the Accellera standard Open Verification Library. It complements the OVL Group website, where OVL is developed.

Foreword by Harry Foster: "The new OVL standard finally fulfills my vision of creating a vendor- and language-independent assertion library that can be leveraged across multiple verification processes". Full text from Harry.

 OVL is the Open Verification Library
  • OVL is an Open standard, developed by Accellera and available from the Downloads area.
  • OVL is a Verification methodology, which can find bugs (even in mature designs)
  • OVL is a Library of predefined assertions, currently available in Verilog, VHDL, SVA and PSL

 OVL provides a Methodology for Assertion Based Verification
  • Easy to use: just add instances in a language you already know
  • Reusable in different parts of the design flow, e.g. from simulation to formal verification
  • Good tool support, due to its availability in several languages
  • Well tested, and can avoid simple coding mistakes (particularly for users new to a language)
  • Future-proof: OVL instances can co-exist with assertions written in a language e.g. PSL, SVA
