ltsview
Visualise a labelled transition system (LTS) using a 3D view.
The tool clusters states based on structural properties. These clusters are then visualised to form a backbone of the LTS on which the states and transitions can be drawn. The tool provides functionalities to explore the visualisation (zooming, panning, rotating), mark deadlocks, mark states based on the values of their state vector parameters and mark transitions based on their labels. An image of the visualisation can also be saved in various bitmap formats. The approach is described in detail in [HWW01].
Note
In contrast to ltsgraph this tool is able to handle large state spaces.
The graph can be rotated by dragging with the right mouse button or dragging with the left mouse button while holding the shift key. Zooming in and out is possible by using the mouse wheel or by dragging the mouse up/down while holding the middle mouse button. The graph can be moved around by holding the “Control” button and dragging with the mouse.
ltsview supports simulation of the system in a way similar to lpsxsim. Simulation can be started from the initial state by clicking “Start” in the simulation window (which can be turned on/off in the “View” menu). By double clicking one of the next states in the simulation window, the simulation progresses to that state.
A useful feature of ltsview is the possibility to find a trace to a state. First, make sure that no simulation is currently running. Turn on the “Display states” option from the “View” menu and select a state by clicking on it. Now start a simulation and click the button “Backtrace”. A trace from the initial state to the selected state will now be shown in the graph. The “Undo” button allows you to step through that trace backwards.

Usage
LTSView [OPTION]... [INFILE]
Description
Start the LTSView application. If INFILE is supplied then the LTS in INFILE is loaded into the application.
- The input format is determined by the contents of INFILE. If that fails, an attempt is made to force the input format based on the file extension. The supported formats with file extensions are:
Aldebaran format (CADP; .aut); GraphViz format (.dot); Finite State Machine format (.fsm); mCRL SVC format (.svc); mCRL2 format (*.lts).
Command line options
--timings[=FILE]
append timing measurements to FILE. Measurements are written to standard error if no FILE is provided
Standard options
-q , --quiet
do not display warning messages
-v , --verbose
display short intermediate messages
-d , --debug
display detailed intermediate messages
--log-level=LEVEL
display intermediate messages up to and including level
-h , --help
display help information
--version
display version information
--help-all
display help information, including hidden and experimental options
