On-Chip Generation of Uniformly Distributed Constrained-Random Stimuli for Post-Silicon Validation

Post-silicon validation is becoming widely adopted because it runs significantly faster than pre-silicon verification and hence it helps uncover subtle design errors that escape to silicon prototypes. However, it is hindered by limited controllability and observability, which makes it challenging to reuse pre-silicon content. In order to enable the reuse of stimuli constraints from pre-silicon verification environments, we present a method that …
