Current extended value set dynamic timing analyzers are not sophisticated enough to detect the subtle timing relationships upon which timing-critical systems depend, and exhaustive simulation achieves very accurate results but at tremendous computational cost. MTV is a simulator that strikes a balance between accuracy and efficiency.MTV is more accurate than other extended value set simulators because it respects the ordering of events. It is more efficient than exhaustive simulators because it efficiently simulates overlapping events and requires only a single waveform to represent a signal. Features of MTV include: elimination of common ambiguity, symbolic delays, correlated delays, and sophisticated algorithms to detect ordered events. This paper concludes with simulation results from the ISCAS85 benchmark suite.
