Conformal-LP : Understanding liberty files.

nitint08
Hi

Conformal can read liberty files but the relevant lowpower special cells
are not recognised until those are specially specified with define_* cpf command.

Since Conformal has all the information of library cells (i.e. AON-cells, retention-
cells, power-switches, iso-cells,level-shifters etc) thus it would be more benefical
if this information can also be provided to the user so that he can correct his
list of cells via relevant define_* commands.

  • Following your sequence, it works.

    Earlier i was doing

          lec -LPXL -verify, read design, read library -liberty <>, read cpf <>.

    With your commands

         set lowpower options -netlist_style logical ------ if not set than default should be picked.

         read commands  ---------- these should be order independent.

         report command

         commit power intent   ----- not used

        analyze power domain  ---- not used

    Do you feel this restrict the CLP to provide information as in my case?

    Please share your thoughts from better awareness. Thanks in advance.
