Warning about 'virtuosoDefaultExtractorSetup'

Majid Rafei

Hi.

I have added a new technology file (tsmcN90nm), When I want to create new library which is attached to this technology I get the following warnings:

*WARNING* (LCE-2011): Cannot determine the function of layer 'PDKREC' in constraint group 'virtuosoDefaultExtractorSetup' of technology library 'tsmcN90rf'. For accurate results during connectivity extraction, set the function to one of the predefined values and reload the technology library.
*WARNING* (LCE-2012): Cannot find the mask number of layer 'PDKREC' in constraint group 'virtuosoDefaultExtractorSetup' of technology library 'tsmcN90rf'. For accurate results during connectivity extraction, set the layer mask number to a correct value and reload the technology library.
*WARNING* (LCE-2012): Cannot find the mask number of layer 'OD' in constraint group 'virtuosoDefaultExtractorSetup' of technology library 'tsmcN90rf'. For accurate results during connectivity extraction, set the layer mask number to a correct value and reload the technology library.
*WARNING* (LCE-2012): Cannot find the mask number of layer 'NW' in constraint group 'virtuosoDefaultExtractorSetup' of technology library 'tsmcN90rf'. For accurate results during connectivity extraction, set the layer mask number to a correct value and reload the technology library.

Please guide me how to fix this.

  • Hi,

    it seems you do not have the necessary information in your tech file.

    Take a look at the "functions" section:

    I have added something that may match your situation

    functions(
     ;( layer                     function        [maskNumber])
     ;( -----                       --------            ------------)
      ( PDKREC              "recognition"        1            )
      ( OD                        "diff"                     2            )
      ( NW                       "nwell"                  3            )
      ......etc

    This should fix the error messages
