MURPHI2SMV(1) General Commands Manual MURPHI2SMV(1) NAME murphi2smv - translate a Murphi model to SMV SYNOPSIS murphi2smv [--output FILE | -o FILE] FILE DESCRIPTION The utility murphi2smv is bundled with the model checker Rumur and can be used to translate a Murphi model into the input format to the NuSMV model checker. See rumur(1) for more information about Rumur or Murphi. OPTIONS --help or -? Display usage information. --numeric-type [integer | word] or -n [integer | word] Set the SMV type used for ranges, scalarsets and numeric liter- als. This can be either integer to use native integers or word to use bit-vectors. If this option is omitted, one is chosen au- tomatically based on the content of the input model. --output FILE or -o FILE Set the path to write the output SMV model to. If this argument is omitted, output is written to standard out. --quiet or -q Silence warning diagnostics. --verbose or -v Report extra debugging information. --version Display version information and exit. NOTES Translation to SMV is imprecise because the semantics of model execu- tion in SMV are significantly different to Murphi. murphi2smv should not be expected to give you a ready-to-run SMV model. Rather it gives you an initial rough translation that you will need to edit to form a runnable model. LIMITATIONS Murphi type declarations have no exact equivalent in SMV. These are handled by propagating and expanding them inline. This is done purely syntactically, which can lead to unexpected or incorrect results if your input model has symbols that shadow other symbols. The following Murphi constructs have no equivalent in SMV and are emit- ted as a placeholder comment: • alias declarations • alias rules • alias statements • assume, cover, and liveness properties • clear statements • error statements • exists expressions • for loops • forall expressions • functions, procedures, and calls to these • if statements • isundefined statements • property statements • quantifiers • record definitions • simple rules • rulesets • switch statements • undefine statements • while statements You will need to either rephrase your input model to avoid these fea- tures or edit the generated SMV after generation. Rumur supports integers up to 64-bit in width. SMV integers are only 32-bit. There are no checks that the numbers or calculations in the input model fit in 32-bit. This may result in constants or calculations in the generated SMV that overflow. Murphi rule-local declarations and variables have no equivalent in SMV. These are emitted using SMV syntax but will need to be moved to a valid location within the SMV output.
