Coverage of formal property specifications has important ramifications in design verification. Mutation coverage, a well studied approach towards specification coverage, checks whether the specification fails in the presence of a fault. Existing mutation coverage methods are broadly divided into those which inject the fault into a given implementation and those which inject the fault directly into...
Automated methods for bug localization for hardware designs typically work on the design implementation to root-cause a given bug. This paper presents a novel debugging approach where instead of using the design implementation in the debugging process, we use causal deduction using formal properties scattered across the design to locate the bug. This has two advantages, namely, (a) the reasoning takes...
Simulation-based techniques are the defacto standard for the verification of industrial designs. Since verification effort takes about 70% of the time of the design phase, it is important to expedite the simulation process in order to reduce the overall verification effort. Modeling-based techniques play an important role towards achieving the speed-up by expediting many subtasks of the overall verification...
