Overview

Questa Post-Silicon Debug

The immediate challenge is “observability” when you suspect a certain cluster or IP is the culprit. The ability to setup particular initial test conditions, probes, and constrained-random stimuli to reach the internal areas of the DUT is a real challenge given the SoC is in its fully realized state.

Key Features

Formally explore all input stimuli and transactions

Once assertions describing the desired behaviors are synthesized into the DUT on-board the hardware-assisted verification platform, the Questa Post-Silicon Debug app leverages the formal-based Questa Property Checking app (PropCheck) to bug hunt for the root cause of the observed failure.
