CMurphi (Caching Murphi) is a model checker developed on the top of Murphi.

The original Murphi web page is here, while a more up-to-date page is here.

CMurphi implements two new model checking algorithms. The first one has been obtained from Murphi 3.1 release by replacing Murphi Hash Table with a Cache and Murphi RAM queue with a disk queue. The second one is disk based. Both are described in STTT 2004.

The current version of CMurphi is a refactored one:

  • it corrects some errors coming out with newer versions of g++
  • it supports 64-bit architectures also when using hash compaction
  • it includes FHP-Murphi
