is there skill code to link a layout to a schematic in VXL

Nhumai

Hi All,

I have a lib 165 cells. Layouts we copy from vendor lib and schematics we constructed them ourselves. Therefore, of course layouts and schematics are not linked and I would like to write a skill code to link them together . Is there any skill code to link layout and schematic ? I at least need to know how layout and schematic link in org skill code, what condition they can link so I can modify the code to work with my need . 

please help 

thanks

    Hi Nhumai

    Perhaps you can try the following:

    procedure( CCSsetConnRef(lib)
       let( ()
          unless( ddGetObj(lib) error("Cannot find lib %s" lib))
          foreach( cell setof(x ddGetObj(lib)~>cells member("layout" x~>views~>name))
             when( ddGetObj(lib cell~>name "schematic")
                printf("Processing cell %s\n" cell~>name)
                lxSetConnRef(lib cell~>name "layout" "CELLVIEW"
                    ?schLib lib ?schCell cell~>name ?schView "schematic")
             ) ;when
          ) ;foreach
          printf("Job done\n")
       ) ;let
    ) ;procedure


    Best regards

    Hi Nhumai,

    What exactly do you mean by "linked"?
    For a given cell you may have any number of schematic and layout views - it's not like a given schematic view has a specific associated layout view.
    Only in VXL a layout cell view has a user defined property (cv~>lxInternal~>source~>view) that containes the information about the schematic that this layout was "generated all" from".

    Hi Max,

    Yes currently since we didn't generate layout from schematic so the VXL is not working for this lib. Even thought those cells lvs is clean still we can't use VXL to place them on the upper level. That is why I interested to learn if there is a way to make them work with VXL . 

    thanks
