Hello,

Version: Cadence 6.1.5.

Technology & Process: GPDK180nm

Verification Check: Assura DRC, LVS

I am Working on Cadence 6.1.5 version. I have designed Double tail comparator. While i am running Assura LVS. In log file i am getting error in Extract Rule File (divaEXT.rul). In log file Error exist in rule file. That is given by Foundry. So i am providing log file can someone help me.

Thanks in Advance,

    Sorry, yes spectre is simulator for schematc. Actually what i am supposed to ask means if schematic is designed but i am not verified with spectre simulator or may be spectre file is missing. If I run LVS will it get results clean if i have done proper connections. I am posting log file please go through it

    I have no idea what you're asking here. If you're asking whether it's possible to get LVS clean results without having simulated the design, then the answer is of course yes - LVS is simply matching the connectivity between the schematic and an extraction of the layout. It knows nothing about whether you've simulated it or not.

    The log file doesn't tell me anything very useful - it just says that it managed to go through all the steps to run LVS. The LVS match report will be elsewhere. I can't write in this post a tutorial on how to run and debug Assura LVS - there should be enough on that in the documentation. Or you should speak to your supervisor - it sounds to me as if you don't really know what you're trying to do here...

    Regards,

    Andrew.
