Title: Calibre PEX problem with UMC 0.13u design kit
Post by grassflying on Apr 17^th, 2008, 10:44am

I am using DRC, LVS and LPE files in Cadence (available from UMC 0.13u design kit). DRC and LVS are running but when I run Calibre-> PEX (Parasitic Extraction) the following error is generated:

"Undefined layer name parameter: NSD_C"

LPE file has definition rules similar to the following given below:

RESISTANCE SHEET NSD_C [7.00 0] MASK
RESISTANCE SHEET PSD_C [7.00 0] MASK
RESISTANCE SHEET PLY_C [8.00 0] MASK

Does anybody know what's the problem due to and how I can fix it? Thanks!

NSD_C is missing from your LVS file. You would need a layer statement that defines the layer NSD_C, or you need to do a boolean operation to generated a derived layer called NSD_C. It would probably be best to contact UMC to get this sorted out.
