Abstract

Here we show that the Event Driven Condition Free (EVCF) simulation technique for gate-level circuits can be extended to the multi-delay timing model. In the multi-delay timing model, gates have different integer delays. Events are produced out of order and must be sorted for processing. The EVCF technique has shown spectacular gains in performance for the zero-delay and unit-delay models. The gains here are somewhat less spectacular, but are substantial, showing that the EVCF technique is an effective method for improving the performance of multi delay simulation.
