How to Use

LaViT: LMNtal Visual Tools

The LaViT IDE should be quite easy to use.

The upper-left pane is for editing programs, while the upper-right pane shows system output.

To run your program, use one of the buttons on the lower-left pane:

LMNtal(Java):

Run the program using the Java runtime.

UNYO(2G), UNYO(3G):

Invoke the 3rd-generation UNYO-UNYO visualizer. (UNYO-UNYO internally uses the Java runtime.)

SLIM:

Run the program using the C runtime.

StateViewer:

Visualize the state-space of the program. StateViewer internally runs SLIM with the --nd (nondeterministic execution) option.

To model-check your program, click the LTL model check tab of the upper-right pane,

and proceed as follows:

• Define propositional symbols that represent properties of states (using the syntax of the left-hand sides of rewrite rules).
• Specify an LTL formula representing the property you wish to check.
• Press the Translate button to compile the formula to a Buchi automaton.
• Press the slim --ltl (or slim --ltl-all or LTL StateViewer) button to check the specified property.

Examples of propositional symbols and LTL formulas can be found by opening the programs under the demo/ltl directory of the distribution.

You can save and load the set of propositional symbols and a LTL formula (that can be numbered from 0 to 9) using the "LTL File" feature on the lower-right.

For further details, see LaViT (in Japanese).
