Assura DRC: How to Define derived layers

stuso

Hi there,

I'm wondering how you define your own variables/derived layers, e.g when i'm using this
command:

    newVia2_a = geomSize( VIA2 0.07 )

However Assura doesn't seem to like that i have not deifined "newVia2_a".

Can someone tell me the syntax to do this, i'm assuming it has to go in the  layerDefs section somehow.

Thanks

  • Hi Stu,

    I don't work with Assura myself, but a few of my colleagues have stated that there does not appear to be any issue with the line of code as it is, but:

    1) Ensure that the statement is in the Rules section, not in the layerDefs section

    2) Ensure that the preceeding statement(s) do not have any errors

     

    One of my colleagues supplied the following sample rules file:

    drcExtractRules(

      layerDefs( "df2"
        VIA2 = layer( "VIA2" )
      );end df2 layerDefs section

      layerDefs( "gds2"
        VIA2 = layer( 14 )
      );end gds2 layerDefs section

      newVia2_a = geomSize( VIA2 0.07 )
      errorLayer( newVia2_a "Enlarged VIA2" )

    );end drcExtractRules

    This compiles correctly.

    I hope that the above information helps you, if not, you may need to send us your rules file for further assistance.

    Regards,

    Lawrence.
