I have an already taped out design that I want to do some logic changes to. I have to use sparecells as we only want to change metal masks. I restore the design, generate an eco file, specify spare cells and use loadECO with the -useSpareCells switch to read in the changes. Originally posted in cdnusers.org by ChrisS
From the documentation I would expect the fe to use the sparecells for the change (so far just inserting an inverter). This does not happen.
