6.1Observability Analysis of Faults Using Sequential Equivalence Checking
Although mutation coverage can point out weakness in the verification environment, the task of analyzing the effect of these non-detected faults and what corrective action to take can be daunting, especially when there are numerous of faults. In this paper, the authors wish to share their experiences in how they applied non-detected faults observability analysis using sequential equivalence checking on 5 real designs and found it useful in saving us time and efforts in the verification signoff process.

6.2Applications of Sequential Logic Equivalence Checking
Sequential Logic Equivalence Checking verifies functional equivalence between two designs. SLEC is different from old Logic Equivalence Checking. The differences between SLEC and LEC are discussed. SLEC has lots of applications and this paper will cover most common usages of SLEC, such as verifying low power clock gating doesn’t break any functions, design behaves the same after optimization, bug fixes/ECO haven’t injected new bugs, safety mechanism can detect and fix random errors, backward compatibility, and some creative ways to use SLEC. We will provide tricks on how to use SLEC efficiently and improve SLEC convergence rate.
