import OpenAccess to Cadence Virtuoso and do LVS check

shva

Hello everyone,

I design a layout with a third-party software (PyCell) which uses OpenAccess. Now I would like to do LVS check in Cadence. My plan is first import the generated oa database file into Virtuoso and use the built-in function to do LVS. But I have some difficulties in doing that. Could anyone give some advice? Thanks a lot.

    I am not familiar with PyCell studio but some googling gave me this:

    Perhaps you can give the above suggestion a try if you have not already done so. Regardless of the lvs tool which you are planning to use (Assura, PVS, etc), I am not sure if the PyCell data can be read in successfully by the tool (because I have never tried it). I think a better strategy would be as follows:

    a. Get Virtuoso to read the PyCells
    b. Create your layout for lvs verification
    c. Flatten it (or export it as gds using ciw:File->Export->Stream)
    d. Do lvs

    Cadence does not support PyCells. We strongly recommend users to code SKILL pcells as their reliability have been proven in numerous tape-outs

    Best regards
