  SMPT (for Satisfiability Modulo Petri Net) is a model checker for
reachability problems in Petri nets. It started as a portfolio of methods to
experiment with symbolic model checking, and was designed to be easily
extended. Some distinctive features are its ability to benefit from structural
reductions and to generate verdict certificates. Our tool is quite mature and
performed well compared to other state-of-the-art tools in the Model Checking
Contest.
