Error while extracting layout.

archive

Dear all,

I get an error when I am trying to extract a layout using Diva. The following is the error.

"Errors exist in the rules file "/sw/cadence/libraries/HCMOS8D//DK_hcmos8d_4.0/Opus/DK_hcmos8d/divaEXT.rul".

Could you please throw some light on where the problem could be. I am using HCMOS8D (0.18u tech) as is evident above.

Thanks and Regards,
Kamesh.

  • Well, that suggests two things:

    1. Your tech file doesn't match the rule file, since there are warnings about the layer purpose pairs being missing.
    2. It is trying to attach parasitics to a device, which has not been extracted. Perhaps you have to turn on some switch to extract the
    devices found with cp1nwC as the recognition layer.

    You may be able to look through the Diva rules file to see if cp1nwC is being used as part of an extractDevice() type statement.

    However, the simplest thing is probably to ask whoever supplied the Design Kit for support. Have you read the documentation that comes with the design kit? (I assume there is some).

    Regards,

    Andrew.
