Abstract

The background for this paper is provided by a mixed signal circuit simulation package. Here, we discuss a number of issues that arose during the course of the logic model design and implementation. We describe a unique method of using inertial cancellation in the detection of set-up and hold time violations in flip-flops and other memory-like elements, and an effective technique of modelling sources so that each queues at most one event at any time. Results are presented showing a test circuit failing to operate correctly as a result of timing violations, correctly simulated by these modelling techniques.
