Generate Package Length Files to be imported into Mentor or Cadence Tools

Pin Delays

Takes an excel file and looks for the two columns "Pin Name" and "Delay". Then reads the rest of the sheet and produces a correctly formatting pin package length file for either Mentor (icdb flows) or Allergo.

You need to do any math in excel prior to running the script to convert the Delay column to the right unit.
