Two new techniques for compiled multi-delay simulation

Two techniques for compiled multidelay simulation are presented. One is event-driven and the other is based on the concept of levelized compiled simulation. Experimental results are presented which show a significant performance improvement for compiled event-driven simulation over interpreted event-driven simulation, although this improvement is somewhat less than would normally be expected. An analysis of both the compiled and interpretive simulators that supports the experimental data is presented. The effects of caching and locality of reference are presented for the compiled event-driven simulator. The performance enhancements for the non-event-driven technique are substantial, but this technique has the disadvantage of generating an enormous amount of code for some circuits. Suggestions for future research are also presented
