generate power grid library

MiladSh

Hi,

I have "qrcTechFile" file from foundry and I want to generate power grid library for dynamic power analysis but in "Set Power Library Mode" menu I don't know what's needed for "LEF-Tech Map" and how can I create a .map file.

Please help me with that.

Thanks in advance,

Milad

    Hi, thanks for your reply.
    Actually I saw your 5min-tutorial for libGen and I have only "qrcTechFile" and don't have any other files that you mentioned there like stdcell.list and spice files. I was thinking only qrcTechFile is necessary but now unfortunately I believe that I can't generate power grid library.

    Regards,

    The std.cell list is something you create, it's just a list of your std cells. You can generate the power grid library without spice, but it will be a bit less accurate.

    So you say that I can generate power grid library with only "qrcTechFile" and ".lef" file?
    And also how can I create a list of std cells?

    You can, but I would ask the library vendor for the extracted spice for the std cells.

    There are probably lots of ways to create the list of std cells. I grep the LEF files for MACRO and then do some file manipulation to get it.
