How to associate an extracted netlist of a subckt to the symbol view in schematic editor.

RFStuff

Dear All,

I am using Calibre ( mentor Graphics). It creates the spectre Netlist and calibre view for PEX.

However, claibre view creation takes a lot of time unlike its spectre Netlist.

The spectre netlist it creates in a file like xyz.pex.netlist.

The format is as below:-

 

simulator lang=spectre
include "SUBCKT_BLOCK.pex.netlist.pex"
subckt SUBCKT_BLOCK (  DVDD DVSS A B C D E \
 F )

        .................................

............................................

............the sub ckt netlist body .............

........................................................

include "SUBCKT_BLOCK.pex.netlist.DIV_BY_4_WITH_GRID.pxi"
//
ends SUBCKT_BLOCK
//
//

 

Is it possible to associate this netlist to the corresponding subckt symbol used in the bigger ckt block the schematic editor so that the created netlist will have the above sub-ckt netlist in the output netlist of the bigger ckt block ?

Kind Regards,

  •  Dear Andrew,

    Thanks a lot for your reply.

    May be I was unable to interprete the steps written in that page. So I am thinking better to post the steps I have alrady done.

    What I want :-

    a) I want to associate the extracted netlist file named  BLOCK.pex.netlist to the symbol BLOCK  ( which is being used in a bigger schematic) only when I want to do PEX simualtion of the entire big schematic.

    b) I should also revert back to normal symbol ( not PEXed netlist) view  when I am not interested in PEX simulation

    What I did is as follows:-

    1) I went to BLOCK_LIB-> BLOCK and copied the symbol of BLOCK  to spectre view. So a spectre view is created which is exactly like the symbol.

    By the way BLOCK_LIB is the library containing the cell  BLOCK. So what I did is:-

    BLOCK_LIB-BLOCK-Symbol   copied to  BLOCK_LIB-BLOCK-Spectre


       

    2) icfb->Tools->CDF->Edit ( CDF prompt came up)

    3) CDF Section->Cell                             CDF Type-> Base

    4) Browsed to the cell containing the symbol BLOCK.

    5) Then went to the Component Prameter Section

            clicked on Add button. Edit CDF Parameter Form came up

                param Type - string

               parseAsNumber- no

              parseAsCEL-yes

             storeDefault-no

             name-model

             prompt-BLOCK

              The remaining field I kept blank

              Clicked on  Apply

    6)    Then I went to Simulation Information Section

          Clicked on Edit button

          Edit Simulation Information Form came up

        Choose Simulator:- spectre

         otherParameters- model

        componentName- 

                             kept blank as suggested in that page, I think, Andrew you are pointing to this ( bang on target) which is by default subcircuit. Am I right ?

         termOrder- pins names filled in the proper order as in the .netlist file. i.e. "A"  "B" "C" "D"

        Rest kept blank

        Clicked on  Apply     

     

    Well That is it !!!

     

    issues:-

    1) The model name is coming as subcrcuit

    2) How I can revert back to the normal symbol view ?

    Kind Regards
