[PATCH v3 09/22] verification/dot2k: Prepare the frontend for LTL inclusion
Posted by Nam Cao 8 months, 1 week ago 
The dot2k tool has some code that can be reused for linear temporal logic
monitor. Prepare its frontend for LTL inclusion:

  1. Rename to be generic: rvgen

  2. Replace the parameter --dot with 2 parameters:
     --class: to specific the monitor class, can be 'da' or 'ltl'
     --spec: the monitor specification file, .dot file for DA, and .ltl
             file for LTL

The old command:

  python3 dot2/dot2k monitor -d wip.dot -t per_cpu

is equivalent to the new commands:

  python3 dot2/dot2k monitor -c da -s wip.dot -t per_cpu

Some more things changed here:

  python3 rvgen monitor -c da -s wip.dot -t per_cpu

For the rest, all changes in the scripts (11-12/22) look good to me.
