On Supporting Sequential Constraints for On-Chip Generation of Post-Silicon Validation Stimuli

Post-silicon validation plays a critical role in exposing design errors in early silicon prototypes. Its effectiveness is conditioned by in-system application of functionally-compliant stimuli for extensive periods of time. This is achieved by expanding on-the-fly randomized functional sequences, which are subjected to user-programmable constraints. In this paper we present a method to extend the existing work for on-chip generation of …
