Zusammenfassung:One embodiment provides a method and a system for generating test vectors for testing a computational system. During operation, the system obtains a design of the computational system, the design comprising an original system. The system generates a design of a fault-augmented system block by adding a plurality of fault-emulating subsystems to the original system; generates a design of an equivalence-checking system based on the original system and the fault-augmented system block; encodes the design of the equivalence-checking system into a logic formula, with variables within the logic formula comprising inputs and outputs of the original system and inputs and outputs of the fault-augmented system block; and solves the logic formula to obtain a test vector used for testing at least one fault in the computational system.
