DRC problem

abdoboua

I couldn't find divaDRC.rul file in my NCSU_TechLib_FreePDK45 technology library, It contains just rule file for calibre (calibreDRC.rul)

Is it a normal thing not to find it?

I tried to install and integrate calibre with cadence virtuoso 617,but I couldn't. It gives me this error:

Environnement variable CALIBRE_HOME is not set.Calibre skill interface not loaded

Your help appreciated.Thank you

    Whether Diva rules are provided or not is a question for NCSU, although it would be fairly unusual for Diva rules to be provided for a 45nm technology; normally if it's a Cadence Physical Verification solution you're after, the choice would be PVS, not Diva.

    Calibre is a Mentor Graphics product, not a Cadence product, so this is not the best place to ask about that. However, the error is fairly clear - it suggests that you need to do:

    setenv CALIBRE_HOME /path/to/CalibreInstallation

    if using csh, or:

    export CALIBRE_HOME=/path/to/CalibreInstallation

    if using bash/ksh

    before starting Virtuoso. I don't know that for certain, but it seems likely to me given the message.

    Regards,

    Andrew.
