Tau -- a lightweight tool for specifying and verifying tiny automata models

Description

Tau is a small Tcl/Tk application that can be used to quickly specify and formally verify small automata models (the name 'tau' is short for 'tiny automata'). It is used as a teaching aid in CS118, a course on the formal verification of asynchronous software systems using logic model checking. Tau requires the availability of a standard C compiler (e.g., gcc) and a recent version of the Spin model checker (e.g., Version 6.4.3 or later) as background tools.
