Assura RC deck working in PVS

nads

Hi all,

We have PVS LVS and QRC tools in company and the only deck available from vendor site  was Assura RC extraction.

Seems Assura deck set does not work good with PVS svdb data, some how created svdb directory using pvs -lvs -qrc_data...got the output spice netlist but seems like it doesnt contain any parasitic information.

Can you please let me know is there a way to make Assura RC deck working in PVS?

Thanks and Regards

  • Hi Ramya

    I think you meant "Assura RC deck" as "QRC techfile". Usually we use the word "deck" for DRC or LVS files and "techfile" for the parasitic extraction file.

    If you have the parasitic techfile for Assura-QRC flow, it is possible to convert it for PVS-QRC flow but this requires quite extensive knowledge of how the layer mapping should be done:

    a. Copy the "design.lvsfile" in PVS LVS run directory into the QRC technology directory as "lvsfile"
    b. Modify the layerSetupFile in QRC directory so that it uses the appropriate LVS layers in the copied lvsfile
    c. Check the last few lines in "RCXspiceINIT" script file for the compilation options and re-do Techgen compilation using the same options
    d. The QRC package is now ready for PVS-QRC flow

    By the way, QRC has already been renamed as "Quantus" for ver14.1 and above.
