How to import a .gds file in Virtuosos with a LAyer-Mapping table/file

RFStuff

 Dear All,

Our package vendoe sent us a .gds file along with Layer Map File.

 I streamed in the .gds file in CADENCE Virtuoso.

I created a new library named PCB_PACKAGE and attached the PDK (the PDK we are using for chip design) technology file to it.
I also added the vendor's  Layer-MAP file during Stream-in of the .gds file. (User-Defined Data ->Layer Map Table:  Layer-MAP file)

.

It successfully streamed in the .gds file. When I opened the layout cells ( let's say one cell in the Laibrary ), the layers are not visible in the virtuoso editor.

I deleted PCB_PACKAGE library and again created it and attached the  PDK technology file.
Then I streamed in the .gds file. This time I didn't give the Layer-map file sent by the vendor.
After stream-in, I found the packages but they are shown in PDK layers.


So, how we can see the layers corresponding to Layer-map file ?

 

Kind Regards,

  • Hi RFStuff

    Using the gds layer map file from the vendor is actually correct. I think you should check the strm-in log file for warnings on dropped layers, etc. Perhaps there are mismatches in gds numbers between the layer map file and the gds file.

    Best regards
    Quek
