NAME
kronos - symbolic verification of real-time systems
SYNOPSIS
kronos options f1 [.tg] [ f2 [.tctl] ]
DESCRIPTION
kronos checks whether a timed automaton satisfies a TCTL-formula.
OPTIONS
-c
kronos creates the file f1.cpt obtained from the input file f1.tg by computing the canonical forms of all constraints on clocks.
-f formula
kronos creates the file aux.tctl containing formula and takes it as the formula.
-g
kronos generates the symbolic reachability graph starting at the initial state. By default, the size of the graph is limited to sim-size. The output is written in the file f1.sim.
-G size
Instead of -g. Changes sim-size to size.
-h
Makes kronos to write the evaluation of every subformula to a file .log. By default, kronos only creates the output file .eval with the result of the overall evaluation. Only for backward reachability.
-r
kronos evaluates the formula using forward reachability. The algorithm generates upto sim-size reachable symbolic states. By default, backward reachability is used.
-R size
Instead of -r. Changes sim-size to size.
-v
Sets to verbose. This option causes information about the progress of the evaluation to be reported to the standard output. By default, kronos runs quietly.
-s step
Sets the time step used to evaluate unbounded au formulas to step. Only for backward reachabilty. By default, kronos uses 1.
INPUT FILES
A timed automaton (.tg file)
A TCTL-formula (.tctl file)
DIAGNOSTIC FILES
Characteristic set of the formula (.eval file)
Characteristic set of every subformula (.log file) [option -h]
Reachability graph (.sim file) [options -g and -G]
Counter-example (path.reach and trace.reach files) [options -r and -R]
OUTPUT FILES
kronos generates the following files for internal use: .kro, .prop, .reg, .lab, .reg.
