Has anyone ever ran into a QRC extraction "RC-coupled" with empty .SUBCKT for macro cell

ttran0671

Hi,

     I'm trying to do a QRC extraction with  "RC-coupled" and after QRC extraction finished, I see that I'm getting empty SUBCKT definition.

 

.subckt  buffd

.ends buffd

 

Has anyone ever encountered this problem with QRC?

 

Thanks

Alan

  • Hi Alan

    It would be good if you can provide the version of QRC so that we can do more debugging on the problem.

    terminal>qrc -version

    It would also be good for you to provide more info on the entire flow:
    a. Are you using Assura-QRC, PVS-QRC or Calibre-QRC flow?
    b. Did you had LVS match?


    Best regards
    Quek
