Concurrent fault co-simulator

Abstract:

Devices, methods, computer-readable media, and other embodiments are described for concurrent functional and fault co-simulation of a circuit design. One embodiment involves accessing simulation data for a circuit design made up of a plurality of machine regions. A plurality of faults is selected from the simulation data for co-simulation operations of functional simulation and fault simulation of the circuit design, and functional simulation of the plurality of machine regions is initiated using the simulation data. A first machine region is identified during the functional simulation as associated with at least a first fault of the plurality of faults. A functional simulation of the first machine region is performed, and a divergence point associated with the first fault is identified. A fault simulation for the first fault is performed using the functional simulation of the first machine region and the divergence point.
