Abstract

We present algorithms and time complexity results for MOS switch-level simulation with particular reference to race detection. Under the switching model used in classical (Boolean) switching theory, we derive a linear-time race detection algorithm for switch-level circuits that have no feedback within a clock phase, and have unit fan-out. We show that the problem becomes NP-complete if fan-out of two or more is allowed. We Also relate this result to others that have recently been reported, using a different switching model.
