Abstract
By providing at least two hardware representations of a specified circuit design, an efficient debugging system is provided that allows 100% design visibility at an extremely reduced simulation time owing to a time-shifted operation of the at least two hardware representations. Upon detection of a specified abort state in the leading hardware representation, the corresponding delayed state of the time-shifted hardware representation may be used for a subsequent simulation of only a relevant portion of the test run that has lead to the specified abort state.
