TransIt

Automatically create transition diagrams of CSP processes.

(click the image for the original which is larger)

The image above shows the transition diagram of the process ATM1 defined in section2-1.csp. The process has been normalized and each node has been labelled with its acceptances. It was generated by TransIt using the following invocation:

transit -na section2-1.csp ATM1 output.png png -Goverlap=orthoxy \
               -Gratio=1.0
  

TransIt supports all output formats supported by GraphViz, including PNG (shown above), PostScript, SVG and XFig, among many others.
