metal pin in layout is showing its actual color

Dear all,

i am using the cadence virtuoso (IC6 version ). when i design the layout from the schematic using tsmc 65nm pdk. All the pins are showing yellow box color. However in actual, every metal is defined with different set of color and boundary combination in the display.drf file.

Can you please help me how to resolve this problem.

Andrew Beckett  can you please help me with the same.

OK, hopefully you resolved the permissions issues we discussed before.

Anyway, the first thing to do is to use Tools→Technology File Manager to dump the tech file from tsmcN65 into (say) tsmcN65.tf. Then look in this file for the techDisplays section. This lists the layer/purpose pairs and the packet, visibility, selectability and various other attributes.

I have a rather old tsmcN65 PDK to hand, and in this technology file the packets are named:

( M1 pin cyanXthickLine2 t t t t t )
( M2 pin goldXthickLine2 t t t t t )
( M3 pin forestXthickLine2 t t t t t )
( M4 pin slateXthickLine2 t t t t t )

Then these are defined in the display.drf at the same location as the tsmcN65 library. Can you check that display.drf to see if whatever packets you have referenced from the tech file are defined in the display.drf which comes with the PDK? My guess is that you have a local display.drf which is from a different technology and hence the packet names don't align with what they are called in the PDK. Otherwise if they were matching they wouldn't show up in yellow (it's probably complaining about missing packets when you open the layout?)

 Andrew Beckett , I have copied the same display.drf file in my local director which is available in  tsmcN65 folder. and content is available like  "

Yes, it's okay to choose 'Select All'. In ASCII Technology File field, you can simply write the name of the file you'd like to be generated. For example, if you type tsmcN65.tf in this field, a new file by this name will be created. In this .tf file, look for M1_pin - do you see this display packet defined for M1 pin? It will be in section:

techDisplays(
;( LayerName Purpose Packet Vis Sel Con2ChgLy DrgEnbl Valid )
;( --------- ------- ------ --- --- --------- ------- ----- )

( M1       pin          M1_pin       t t t t t )

 Saloni Chhabra  Andrew Beckett , I followed the same process as told by you and the problem is resolved. Thanks a lot.
