Need workaround for duplicate veriloga module name issue

JKupanna

Hi,

For some reason I'm including the same model file twice in a spectre simulation. In that .scs file I have a ahdl_include statement that includes a varilog-a model. Now because I'm loading this file twice, It is throwing an error saying that

"A built-in or regular master with name xyz already exists, cannot create an alias master with same name"

 Is there a option similar to duplicate_subckt=warning for verilog-a model.

 Thanks,

Jagadish

  • Jagadish,

    Which version of spectre are you using? ("spectre -W" will tell you, or it's at the top of the output file that spectre produces).

    For me, I have a module called forum which I ahdl_include twice, and I get:

    Warning from spectre during circuit read-in.
        WARNING (SFE-2654): VerilogA module `forum' override primitive/(verilogA module) `forum'.

    That said, there is an option, duplicate_module which controls this. If set to error, it errors out. According to spectre -h options, error should be the default, but it appears to actually warn for me.

    This option was introduced in MMSIM12.1 ISR13 (the latest hotfix). Before that (as far as I can tell) it didn't tell you anything about duplicates. 

    Maybe your module name is using a reserved name? Not sure...

    Regards,

    Andrew.
