UPF to CPF conversion

vicky

Is there any utility which would do a conversion of an UPF file to CPF file. I have a testcase which has been implemented using UPF and now I am planning to implement the same using CPF. I did a manual conversion of the commands to create the power domains  but I feel that the way the switch cells and isloation cells are defined in the CPF and UPF is very difficult to convert from it.

  • Sorry Betty I misunderstood your questions.  to read in a UPF and convert it to a CPF you will need to read it in and write out the corresponding *.cpf by adding instructions to do so in the *.do file that you pass to CLP.  The script would be something like the following:

     CLP.do script

    ---------------------

    set lowpower option -netlist_style logical

    read library -liberty path/to/design.lib

    read design <hdl_files>

    read power intent -upf path/to/my.upf

    write power intent -cpf path/to/my.cpf

     

    Btw, the *.lib is required because the UPF related power intent information is included in the *.lib in addition to the *.upf.

    Let me know if that helps

    Best regards,
    Mickey
