Technology translation in RC

archive

Hello,

Anybody know how to do technology translation in RC like DC allows? That is, given a netlist mapped in one technology library, can I map it to a different technology witout resynthesizing?

I think DC had a translate command, does RC have anything similar?

Thanks,

  • DC does have a translate command and as higliighted by sporadic _crash it doesn't give you an optimized netlist (but you can run the optimization once the translation is done)

    The way it works is that you don't have to have cell to cell mapping for the combinatorial but if you have some exotic cells it's a good idea to have it otherwise after tyranslation you have to do a lot of cleanup.

    For RC I will suggest to do the following.

    setup library 1
    read your netlist
    unmap it (back to GTECH)
    remove library 1 setup and setup library 2
    map your design to library 2

    The sequence above should "translate" your design from library 1 to library 2.

    I will have to look into the documetation if you need more specific command but this is the generic idea.

    Thanks,
    Eric.
