Pre-silicon fuzzing

Concept

**Pre-silicon fuzzing** is the application of fuzz-testing techniques to hardware designs before fabrication, with the goal of exposing design bugs or security weaknesses while the processor or hardware block is still available as a model, simulator, or register-transfer-level design. In processor-security research, recent work extends pre-silicon fuzzing beyond functional-correctness testing toward **security-oriented fuzzing**, including detection of side-channel leakage against formal hardware-software leakage contracts.[^geier-abstract]

Pre-silicon fuzzing

Pre-silicon fuzzing is the application of fuzz-testing techniques to hardware designs before fabrication, with the goal of exposing design bugs or security weaknesses while the processor or hardware block is still available as a model, simulator, or register-transfer-level design. In processor-security research, recent work extends pre-silicon fuzzing beyond functional-correctness testing toward security-oriented fuzzing, including detection of side-channel leakage against formal hardware-software leakage contracts.[1]
