check_spec - Perform fair CTL model checking.


check_spec [-h] [-m | -o output-file] [ctl-expression]

Evaluates SPEC statements. If no ctl-expression is given at command line, then the command evaluates the previously parsed SPEC statements, if any. If a formula is false, a path witnessing its falsity is printed. Infinite paths are represented by a finite sequence of states leading to a cycle.

Command options:

-m
Pipes the output generated by the command in processing SPECs to the program specified by the PAGER shell variable if defined, else through the UNIX "more" command.
-o output-file
Writes the output generated by the command in processing SPECs to the file output-file.
ctl-expression
A CTL formula to be checked.

If the ag_only_search environment variable has been set, and the set of reachable states has been already computed, then a specialized algorithm to check AG formulas is used instead of the standard model checking algorithms.
