How to flatten layout cells and preserve pin names when pin names from different cells are the same

twen

I am using virtuoso version 6.1.6-64b 12/07/2015 20:18 (sjfbm186) .

Suppose I have a top level cell T, and T contains two cells A and B, and there are a pin called P in both A and B. When I flatten cells A and B by gui (Preserve pins, preserve ROD Objects) to by foreach(s list(dbA dbB) dbFlattenInst(s 1 t t t t t t t)), the pin P in cell A is brought up into cell T without any problem. However, the label on pin P in cell B is renamed to something like dbNet032. I see this can be useful in certain cases, but it is not what I want.

Is there anyway that I can flatten A and B and brought up the pin P to cell T and keep both pins' label as it was?

Thanks in advance,

TJ

    Hi, Andrew,

    I am impressed that the program your wrote 18 year ago is still working and is sort of working in my case!

    I am wondering if you could create a new version of dbFlattenInst() instead of wrapping around the existing dbFlattenInst() so you do not need to do the renaming and deleting, provided that the existing dbFlattenInst() is not thousands-line long and would not take you too long?
