Abstract

The modelling of delay-insensitive asynchronous circuits in the process calculus CCS is addressed. MUST-testing (rather than bisimulation) is found to support verification both of file property of delay-insensitivity and of design by stepwise refinement. Automated verification is possible with a well-known tool, the Edinburgh Concurrency Workbench.
