We give the description of a verification tool taking boolean programs of guarded commands as input; internal representation of programs are sets of Binary Decision Diagrams (BDD) (one for each guarded command). It allows to construct an abstract program of the same form obtained using an abstraction relation given by a boolean expression on “concrete”’ and “abstract” variables. The tool allows the verification of CTL formulas on programs. We illustrate its possibilities on an example.
