CTL model checking

CTL model checking, implemented using BDDs (JavaBDD library).

Build Status

Usage

Usage: program (CTL specification) (path to model file)
e.g.: program 'AG(Not(And("c1"="T", "c2"="T")))' "model.fsm"

Arguments:

  1. CTL specification (e.g. Imply(AG("t1"="T"), AF("c1"="T")));
  2. path to model file, in the FSM format with the following restriction:
    • all the states must be univocally identified by the value of their atomic propositions.

Quick start

  1. Install Scala and sbt
  2. Run tests with make test
  3. Prepare jar package with make package
  4. Run demo with java -jar /path/to/ctl-model-checking.jar 'AG(Not(And("c1"="T", "c2"="T")))' ./src/test/resources/mutual-exclusion.fsm

Example (output)

=== CTL Model Checking ===
(*) Parsing CTL specification AG(Not(And("c1"="T", "c2"="T"))) ...
(*) Parsing FSM model ./src/test/resources/mutual-exclusion.fsm ...
 - 9 atomic propositions
 - 9 states
 - 14 transitions
(*) Model checking...
[OK] The model satisfies the specification
