    First of all there's no "foundry" with gpdk180 - it's a Generic 0.18um PDK provided by Cadence intended to illustrate flows, rather than being a real process.

    Secondly, you're using the Diva rules with Assura. That won't work. I don't know why you're doing that, when gpdk180 contains the Assura rules...

    In the gpdk180 installation, there should be a file called "assura_tech.lib". In your working directory, create a file called assura_tech.lib with this content:

    INCLUDE /path/to/gpdk180installation/assura_tech.lib

    and then Assura should be able to pick up the rule data easily enough.

    Regards,

    Andrew
