Title: Applying Functional Qualification to Measure the Effectiveness of Formal Verification Environments


Functional qualification – the process of finding weaknesses in and measuring the effectiveness of a verification environment through a fault injection process – has become an accepted and sometimes required aspect of verification since it was pioneered by the Certitude™ product from SpringSoft in 2005.  This unique approach is in daily use by companies worldwide to assess and improve their simulation environments.  The same approach can be applied to formal verification environments.  Given a set of properties, if the RTL functionality is changed through the injection of a fault yet all of the properties still “pass” when proven by a formal verification tool, what does it indicate – a missing property, an incorrectly-described property, an over-constrained environment?  This presentation will explore how functional qualification can be extended to assess and improve formal verification environments to provide a unique perspective on their completeness and correctness.
