Two new techniques for compiled multi-delay logic simulation

Abstract

The authors describe two techniques for compiled event driven multidelay logic simulation that provide significant performance improvements over interpreted multidelay logic simulation. These two techniques are based on the concept of retargetable branch instructions that can be used to switch segments of code into and out of the instruction stream. The second algorithm, called the shadow technique, has been designed especially for systems with instruction caches. Benchmark experiments showed that these two techniques were up to 15 times faster than the interpreted multidelay simulator, with an average improvement of about five times for the fastest method.<>
