In order to call the same routine from the command line, run this tcl…

VOV: Clear out old vovprojects
When you create a new NetworkComputer queue or a new FlowTracer project, each time, the system creates a registry entry and directory in the SWD. At a certain point, you may have hundreds of these. While these projects do not affect performance, they can clutter things up and take up much needed space. It's best to do some…

What is VOV on FlowTracer?
FlowTracer is derived from the system VOV originally developed at UC-Berkeley. The word VOV is not an acronym, but can be thought of as a contraction of the work “Evolve”, as your design flow evolves as the design progresses toward completion. Because of this heritage, many utilities in FlowTracer have a name that begins…
