High-level decision diagrams for improving simulation performance of digital systems

Résumé

Decision diagrams (DD) present a suitable way for the digital system representation efficiently used in several steps of the entire design cycle : design verification, testing, test pattern generation and fault simulation. This paper presents some ways to optimize the decision diagram representation aimed at improving simulation efficiency. Two new types of diagrams are introduced : vector decision diagrams (VDDs) and compressed VDDs, as an efficient and concise model of the system behavior, which preserves all the advantes of the decision diagrams. In order to fully exploit the advantages of DDs new simulatioan algorithms based on cycle-based forward event-driven and recursive back-tracing techniques are proposed. The experimental results of the comparison of different types of DDs as well as of different simulation algorithms on DDs are included.
