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.

Concurrent fault co-simulator

The present disclosure relates to a system and method for debugging in fault simulation associated with an electronic design. Embodiments may include receiving, using at least one processor, an electronic design and performing concurrent fault simulation on a fault to be analyzed associated with the electronic circuit design, wherein the fault has a fault propagation path associated therewith. Embodiments may also include identifying a trace of one or more signals of interest that are in the fault propagation path and generating a faulty database and a good database associated with the one or more signals of interest that are in the fault propagation path. Embodiments may further include identifying one or more differences between the faulty database and the good database.
