This paper studies the problem of coverage management with two emerging formalisms in simulation based validation, namely formal specification of test points and the use of inline temporal assertions. We present methods for checking whether a test-bench with inline assertion covers a set of formal test points. This is particularly useful in developing verification IPs for standard on-chip protocols...
This paper explores the utility of making use of previously proved component properties and available simulation traces at the component and system level of a composite design for proving a newly added architectural property of the design. We present two techniques of reusing these prior verification results for proving or disproving the architectural property without doing full-scale formal verification...
Counter-example guided abstraction refinement (CEGAR) techniques have been primarily used to scale the capacity of formal property verification. This paper explores the utility of CEGAR for verifying an emerging style of formal specifications, called AuxSM+properties, which consists of auxiliary state machines (AuxSMs) and formal properties based on the AuxSMs. A core challenge in formally verifying...
