    ADExl problem with bus notation Reply

    Running a spectre simulation from adexl I am getting this error:

    Error found by spectre during circuit read-in.
        ERROR (SFE-874): "input.scs" 3633: Unexpected operator ">". Expected end of
            file or end of line.

    The interesting part of scs netlist is listed below. Please note that the \ escape was applied to the netlist but not to the output signals. I don't know why.

    I tried the \ escape on the "Outputs Setup" pane but then I could not check the save box. Thus, I assume I cannot enter the signals with the \ escape in the outputs setup pane. How can I getaround that problem?

     Which subversion of virtuoso are you using? (Help->About in the CIW will tell you this, or typing getVersion(t) in the CIW)

    In addition, what do you get if you type:

    envGetVal("asimenv" "mappingMode")

    in the CIW?

    I have ICADV12.1-64b.500.6

    envGetVal("asimenv" "mappingMode") -> "nmp"

    Got further with the problem:

    the output signal was missing the preceeding / on the "Outputs Setup" pane.

    e.g.   Icore/RWL_B0_WN<0>

    With the signal name changed to  /Icore/RWL_B0_WN<0> the simulation ran to completion.

    The input.scs file now has it in the save statement as Icore.RWL_B0_WN\<0\>

     But now, when double clicking on the output I get this message:

    ERROR (WIA-1006): Unable to plot expression <VT("/Icore/RWL_B0_WN<0>" .....

    *Warning* Wave1 is not a waveform object that can be displayed and
              will be DELETED automatically.
              name: "/Icore/RWL_B0_WN<0>"
