Formal verification · a symbolic model checker

created · updated

A program that checks models written in TLA+ and Quint. It turns them into a set of conditions and hands them to an SMT solver, for example Z3, which reasons about all executions up to a given length at once. It outputs the chain of steps where a rule breaks.
