Abstract

VERSA is a tool that assists in the algebraic analysis of real-time systems. It is based on ACSR, a timed process algebra designed to express resource-bound real-time distributed systems. VERSA supports the analysis of real-time processes through algebraic rewriting, interactive execution, and equivalence testing. This paper begins by presenting a brief overview of the process algebra ACSR, its syntax, operational semantics, and equivalence relations. VERSA'S process and command syntax, its algebraic rewrite system, and its state-based analysis features are described fully. The presentation includes examples that illustrate the salient features of ACSR, and output from sample VERSA sessions that demonstrate the application of the tool to real-time systems analysis.
