RTL Compiler, Min Libraries and CPF

 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*/*

 Hi steven ,

      I have a same type of problem,

i have written a code for inverter chain and synthesized using slow and fast lib sepaerately,which represents slow path and fast path helpful in timing analysis.

problem is how can i use this fast lib and slow lib together so that me inverter chain should select perticilar cells from slow lib for slow path and perticular cells from fast lib for fastpath simulataneously in the same module.

Please help in this regard.

 The solution provided should address your issues. Please let us know if it does not and provide additiional information on the issue you are seeing. In the context of EDI, you can also provide timing information through your view definition. Remember synthesis only requires a subset of the information needed for signoff analysis in most cases so it is not unusual for the P&R and signoff steps to add additional information needed such as hold analysis libraries, noise margins, etc.
