Then I run the awk script I wrote with the script produced filename as its only argument and it produces an 'expect' script which then reruns my interactive trace for me automatically. It only works for spin not xspin, because I don't know how to invoke the tk menus from the script. I may just put a pause in the expect script and call up the interactive simulation mode 'manually' and then throw the input at it. Typing 'exp.awk ' produces an executable file named ' .inter'. Running that file will reproduce the last interactive session.
Control is handed back to the user once the script ends.
In order to demonstrate the benefits of formal methods for industrial applications, and to evaluate and compare existing approaches for constructing and verifying control software for reactive systems, FZI launched the Case Study Production Cell in 1993 as an activity inside the German Korso Project. Several approaches have already been applied and lead to succesfull Contributions . The controller is able to accept upto 8 blanks in the cell. The liveness property, as appearing in the task description document has been verified for the whole cell and the whole cycle, as well as weaker forms for each cell element or subset of elements in loop.
