    -binding flag is ignored by ncelab Reply

    Hi all

    I am using IUS 11.1 and having problem with the -binding flag at the ncelab.

    The ncelab ignores this flag and issues the next warning:

    ncelab: *W,BINDIG: -binding ignored for verilog units.

    In the past and in old versions i didn't have any problem binding verilog modules with this flag.

    I will happy to hear from someone who faced this problem or know how to solve it.

    Regards.

    Eyal.

    The extended help for that message says:

    % nchelp ncelab BINDIG
    nchelp: 09.20-s055: (c) Copyright 1995-2012 Cadence Design Systems, Inc.
    ncelab/BINDIG =
            The elaborator has been invoked with the -XLMODE flag. It is assumed
            that the -XLMODE option builds a list for all verilog bindings at the
            parse time. This option will not override any of the bindings set in
            place by the parser.

    If you share your command line we might be able to figure out why the elaborator is being passed the -xlmode flag.

    Hi TAM1

    Thanks for the quick response.

    I am familiar with the extended help message you posted, it was also been suggested by the Ncbrowse tool.

    I am not using the -XLMODE flag in my irun command and as far as I know it is invoked within the Ncelab internally.

    I attaching my irun log to this post , tell me if it tells you something that I am missing (sorry for the length of it).

    Regards.

    Eyal.

    Re: -binding flag is ignored by ncelab Reply

    Apparently the -xlmode switch is passed from 'irun' to 'ncelab' telling the tool that it was invoked in single-step mode and to use the old 'verilog-xl' method of resolving modules. I had access to some really old software as far back as 2008 and every time I used 'irun' and "-binding" I got that warning message.

    You could override it using a Verilog configuration, I guess. But that's more complex than I can describe in a forum posting.
