About

Zetav

Zetav is a tool for verification of systems specified in RT-Logic language.

Verif

Verif is a tool for verification and computation trace analysis of systems described using the Modechart formalism. It can also generate a set of restricted RT-Logic formulae from a Modechart specification which can be used in Zetav.

Usage

Zetav

With default configuration file write the system specification (SP) to the sp-formulas.in file and the checked property (security assertion, SA) to the sa-formulas.in file. Launch zetav-verifier.exe to begin the verification.

Verif

With the default configuration example files and outputs are load/stored to archive root directory. But using file-browser you are free to select any needed location. To begin launch run.bat (windows) or run.sh (linux / unix). Select Modechart designer and create Modechart model or load it from file.

Input Format

Zetav

The Zetav verifier expects the input RRTL formulae to be in the following form:

<rrtlformula>    : <formula> [ CONNECTIVE <formula> ] ...

<formula>        : <predicate> | NOT <formula> | <quantifiedvars> <formula> | ( <formula> )

<predicate>      : <function> PRED_SYMB <function>

<function>       : <function> FUNC_SYMB <function> | @( ACTION_TYPE ACTION , term ) | CONSTANT

<quantifiedvars> : QUANTIFIER VARIABLE [ QUANTIFIER VARIABLE ] ...
Where predicate symbols (PRED_SYMB) could be inequality operators <, =<, =, >=, >, function symbols (FUNC_SYMB) could be basic + and - operators, action type (ACTION_TYPE) could be starting action (^), stop action ($), transition action (%) and external action (#). Quantifier symbols (QUANTIFIER) could be either an universal quantifier (forall, V) or an existential quantifier (exists, E). Connectives (CONNECTIVE) could be conjunction (and, &, /\), disjunction (or, |, \/), or implication (imply, ->). All variables (VARIABLE) must start with a lower case letter and all actions (ACTION) with an upper case letter. Constants (CONSTANT) could be positive or negative number. RRTL formulae in the input file must be separated using semicolon (;).

An example could look like this:
V t V u (
  ( @(% TrainApproach, t) + 45 =< @(% Crossing, u) /\
    @(% Crossing, u) < @(% TrainApproach, t) + 60
  )
  ->
  ( @($ Downgate, t) =< @(% Crossing, u) /\
    @(% Crossing, u) =< @($ Downgate, t) + 45
  )
)

Verif

Verif tool does not deal with direct input. Examples are load from files with extension MCH. Those files are in XML and describes model modes structure and transition between modes. There is no need to directly modify those files. But in some cases it is possible to make some small changes manualy or generate Modechart models in another tool.
