Petri Nets and Speed Independent design Petri nets are investigated as one method of modeling speed independent asynchronous circuits. A study of circuit realizations of Petri nets leads to a demonstration of their usefulness in modeling speed independent operation. This usefulness is emphasized by the design of a speed independent processor from modules developed in the investigation of Petri net implementation.
