Forum Post: RE: Term net name changing for the pins automation using SKILL code
Odin, You would need to use dbMakeNet() to create a net with the new name, and then use dbMergeNet to merge the existing net onto that new net (only the new net then survives). Regards, Andrew

I've been meaning to reply to this thread for a while - just hadn't got to it. In general, the portOrder is not that important nowadays and it's debatable whether all the consistency checks are...

Yes - Inside the cross section editor try Export - Cross Section Technology File, then to import open cross section and use Import - Cross Section Technology File

You might wanna look at "ignore pin" too. By excluding the pins, the tool will not consider the leaf pins for skew balancing and clock drc fixing. Whereas, by using "ignore pin" on them, they would be...

I ran this in 16.6 and got 122 ohms. I noticed you have an etch factor of 90 in Cadence which is impossible. Try 45. I cross-checked in Polar and got an impedance near Cadence. Saturn is good but there...

Not without scheduling, you can add a T Point during this process which can be positioned directly onto the via. That way you can pick the T point when you create your Pin Pairs
