Directed Testing
ConceptDirected testing is a structured stimulus technique used in RISC-V processor verification to target specific architectural features, compliance requirements, and coverage gaps. Evidence describes it as complementary to constrained-random testing: directed tests provide precision and systematic validation, while random stimulus explores unexpected interactions.

Directed Testing
Directed testing is a structured stimulus technique used in RISC-V processor verification to exercise specific architectural features, compliance scenarios, and coverage gaps. In the cited verification flow, directed tests are contrasted with random stimulus: random testing explores broad state spaces and can uncover unanticipated behaviors, while directed testing provides structure and systematic feature validation. The evidence also notes a limitation: directed tests may miss unexpected interactions, so they are most effective when combined with constrained-random stimulus. [Directed testing role]
