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,

  • I suspect you original problem was caused by adding a parameter "model" but not giving a value to the model parameter, and then it reverts to the default behaviour of using the componentName.

    Anyway, if you want to switch between the schematic and your "spectre" view, you can do one of two things:

    1. Use the hierarchy editor to create a config view for your design and then pick the "view to use" for the block in question. Then simulate in ADE from the configured design (open the config and make that the design in ADE).
    2. Use the switch view list in Setup->Environment in ADE and put "schematic" ahead of "spectre".
