RTL Compiler, Min Libraries and CPF

moogyd

Hi,

For synthesis (RTL compiler) I define a worst case libraries read_cpf -libraries, and in the CPF I use

define_library_set -name my_lib_set _librares {libA_slow.lib libB_slow.lib libC_worst.lib}

 i.e. I load multiple worst case librarie (there are actually about 15, from different vendors)

I then export the CPF for the backedn. This works, but....

My backend engineer  is complaining that the CPF file does not contain the min libraries.In principle, I just add then in the same way, but I need RTL compiler to ignore the min libraries.

How do people usually manage this issue ?

Thanks for suggestions/links

Steven

  •  You have 2 choices. If using golden CPF as source to both RC and EDI, you can do

     . . .

    set_cpf_version 1.1

    define_library_set -name wcTim -libraries [concat $stdcell(timing,$pvt(cell,wcTim)) $memory(timing,$pvt(mem,wcTim))]
    define_library_set -name wcPow -libraries [concat $stdcell(timing,$pvt(cell,wcPow)) $memory(timing,$pvt(mem,wcPow))]

    if {[regexp -nocase {/(edi|encounter)$} [info nameofexecutable]]} {
        define_library_set -name bcTim      -libraries [concat $stdcell(timing,$pvt(cell,bcTim))  $memory(timing,$pvt(mem,bcTim))]
        define_library_set -name typ        -libraries [concat $stdcell(timing,$pvt(cell,typ))    $memory(timing,$pvt(mem,typ))]
    }
    . . .

    so certain library sets will only be enabled when read by tools of your choice

    If relying on RC generated CPF for downstream tools you can ready everything in and then in RC you can remove them or set avoids/dont_use in all cells from those set along the lines of

     

    set_attr avoid true *bcTim*/*
