Abstract

See full text

Embodiments provide systems, devices, methods, and machine-readable medium for automated debugging of a design under test in a verification environment as part of electronic design automation. Embodiments may automatically identify inputs that are relevant to a bug for a device under test. A failing test run may be taken and rerun several times with small changes in the inputs. If the test is passing, the mutated inputs may be important to reproduce the bug and may be marked as “suspicious”. The result of this process may be a list of suspicious inputs and a shorter and simpler test that still fails. The shorter test may be rerun and fields of the inputs recorded. New tests may be created with mutated fields. Mutated fields that result in passing tests may be considered suspicious fields. Suspicious inputs and fields may be presented to a user as part of an electronic design process.
