Coverage Unreachability UNR App - Rapid Adoption Kit

The Cadence Incisive Enterprise Verifier (IEV) team recently developed a self-help training kit - a Rapid Adoption Kit - to help users gain practical experience applying IEV's Coverage Unreachability (UNR) App. The RAK also helps users see the benefits of different approaches, UNR flow with and without initialization. The "Coverage Unreachability UNR App" RAK is now available on Cadence Online Support.

 

 

Given an existing simulation environment, assertions are automatically generated from the code coverage holes and formal analysis is used to detect any unreachables. Unreachable code coverage is detected with each approach and results are compared between runs using IMC to locate and view the unreachables. You will also learn how to set up the simulation to collect code coverage and dump a minimal reset waveform for initializing the UNR proof.

 

The key objective is to familiarize the user with the flow, by running:

1. Simulation to generate the coverage database (and optional waveform for formal analysis initialization)

2. Formal analysis on the simulation code coverage to detect the unreachables and generate an unreachables database with two setups: basic uninitialized and initialized

3. IMC to merge the generated unreachables database into the original simulation database and load the merged database to view and accept the unreachables
