> Have you rebuilt gem5?
After rebuilding Gem5, the changes to the "dot_writer.py" are activated. I'll
poke around here and see what I can find.. not sure what's wrong with it yet.
Thanks much,

I have rebuilt after installing pydot, but I don't remember if I did after

I will rebuild again just to be sure.
Thanks much for your help with this.
