Quickstart

To run it you need:

  • required to run VARDA: SWI Prolog
  • needed to build visual models GraphViz
  • needed for automatic visualisation: ImageMagick and GNU Bash (Warning: under Unix, you need GNU bash as a default Bourne shell (/bin/sh) – this is not the case with Ubuntu!!! it ships dash, change it: sudo dpkg-reconfigure dash and answer No to the question: Install dash as /bin/sh?, or uninstall dash.)

GNU/Linux

To use it:

cd varda
./varda

You can load an example model from the cmdline:

./varda therm-model.pl

In Varda, try hlp.

While working in Varda you are in the pure SWI shell, just use Prolog :-)

If you want to load a model when you are in VARDA simply use:

?- [therm-model].

Models:

  • therm-model.pl the hekate_case_thermostat
  • userv-model-alpha.pl the UServ case.
  • elevator-model.pl an example elavator system.

Batch mode

In a Unix shell it is possible to use VARDA in a batch mode, specifying goal from the commandline, e.g.:

./varda hekate_case_thermostat-model.pl -t sar.

Windows

If you use Windows, you can still use VARDA, but automatic visualization would not work (it requires a Unix-like environment). Just run SWI Prolog, and:

?- [varda].
?- [therm-model].

If you have Graphviz under Windows, you can generate pictures manually, e.g.:

?- sar('therm-ard.dot').
?- shi('therm-tph.dot').
?- gax.
?- sxt('therm-xtt.dot').

And then run Graphviz DOT:

dot -T png therm-ard.dot > therm-ard.png

FAQ

ARD Design Levels

In ARD+ you can directly see anly the most detailed (last level). If you want to see previous levels, you can either:

  • comment out parts of the model
  • hic to previous levels in VARDA

If you want to manually collapse the history, and display the ARD and TPH, use: ard_hist_collapse insteand of hic and then sar and shi.
