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. 

  • Hi Betty, PIA is now integrated directly into the CLP user interface. When in the CLP gui (lec -lp –verify –gui) in the upper left pane, expand the Design Setup section and click on Power Spec. This is where you can enter the appropriate power intent content. Best regards, Mickey
  • Hi, Mickey:

    So right now this is no direct UPF-CPF conversion, such as a script running automatically convert UPF to CFF, but rather

    Input specs into the GUI upon the UPF to create a CPF file. Am I right?

    Thanks again,

    Betty

  • 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 

  • Can't we directly use UPF file  for low power simulations ? if so, what are the ncelab options ? i am not using irun, some people use -lps_1801, what is this option

    thanks in advance
