Adding dummy elements to the layout

NorNand

Hi,

I started my layout design and for the matching purpose, I need to add dummy elements like transistors, resistors. whenever I add an instance as a dummy in the layout the LVS will complain that this element doesn't match to the schematic, Then I need to put that instance in the schematic as well, but this procedure makes my design longer.

I believe that there is some tool in Cadence Layout XL that is concerned with adding dummy elements and I hope you could help me with. Or if there is no such tool then at least how to ignore elements in the Layout from LVS

Thanks

    Hi,

    in the "Cadence Virtuoso Layout Suite XL User Guide" there is a section called "Creating Dummy Instances".
    Maybe you can find there what you want.

    Kind regards

    Matthias

    It does tend to help if you actually explain what your problem is - "I face a problem" doesn't really explain what the issue is!

    Regards,

    Andrew.

    Hi Andrew

    I read the help from Cadence, they explained about something called Model Generator, I think it is a special tool, but I am working with Layout XL editor.

    Thanks
