Automated Debugging of SystemVerilog Assertions

In the last decade, functional verification has become a major bottleneck in the design flow. To relieve this growing burden, assertion-based verification has gained popularity as a means to increase the quality and efficiency of verification. Although robust, the adoption of assertion-based verification poses new challenges to debugging due to presence of errors in the assertions. These unique challenges necessitate a departure from past automated circuit debugging techniques which are shown to be ineffective. In this paper, the authors present a methodology, mutation model and additional techniques to debug errors in SystemVerilog assertions. The methodology uses the failing assertion, counterexample and mutation model to produce alternative properties that are verified against the design.
