Configuring new PDK

Vishnuram

I was configuring the new PDK in Cadence virtuoso version IC6.1.4.500.12( one PDK is already existing in the home directory). so i make a new folder(named "new_PDK") in the home directory and added the files(cadence.cshrc, cds.lib, .cdsinit, .cdsenv, bindkeys and the PDK folder). when i source the cadence.cshrc file from from folder new_PDK, i am listing out the problems i am facing:

 

1. its shows techfile conflict

" there is a conflict in techfile graph

  Look at techfile reported error massage in CIW

  correct techfile conflict before proceeding "

 

  Whill loading the files, it takes techfile.tf, pdkutil and display.drf file from PDK folder olny.

 

2. In the schematic window, i can call the instances but unable to connect using wires(wires are not coming. rest all shortcut keys are working.

 

3. In the layer selection windows(LSW) palletes are not visible.

" (LE-101804): Cannot get valid layer form LSW window. "

 

   i can see the layer when i click on layer but again shows blank when i scroll it down.

 

4. Cadence windows crash when i try to make any layer in the layout.

"  \o (LE-101804): Cannot get valid layer form LSW window.
   \a leSetLSWBBox(list(57:328 207:1028)) "

 

Everthing working properly with the old PDK exist in home directory.

 

Please help me out.

  •  I would suspect that this conflict is causing the problem or it may be an issue with the dbuPerUU on the viewTypes (usually the layout viewType). I don't have access to Virtuoso at this time, I'm on holiday, but check the dbuPerUU and the mfgGridResolution in both techfiles (dump the techfiles if you don't have a .tf) and post the relevant sections here.

    *WARNING* (TECH-2000178): A Default Manufacturing Grid conflict has been detected in the technology hierarchy.

    It is caused by the following list of Libraries: silterraB18V; cdsDefTechLib;
