Bayesian Network-Based Test Generation

Concept

Bayesian Network-Based Test Generation is a coverage-guided test-program generation approach that uses Bayesian networks as the underlying machine learning model to steer the generation of test stimuli toward uncovered portions of the design-under-test. It is positioned among model-based and machine-learning-driven test-generation techniques, alongside other approaches that use other machine-learning methods or fuzzing. The concept is cited as related-work reference [10] within RISC-V compliance and verification literature.

Definition

Bayesian Network-Based Test Generation refers to a family of coverage-guided test-program generation techniques in which a Bayesian network is used as the probabilistic model that drives the selection and mutation of test stimuli. The Bayesian network encodes dependencies among test parameters and coverage feedback, allowing the generator to bias new tests toward parts of the design that remain uncovered.
