can't plot waveform while simulating in cadence virtuoso via spectre

leangineer
Hello!

I can't plot waveform while simulating in cadence virtuoso IC 6.1.5 via spectre.

When I initiate Netlist and Run (green button), these are the results:

Delete psf data in /home/eda/simulation/R_div/spectre/schematic/psf.
generate netlist...
Begin Incremental Netlisting Apr 6 23:23:36 2014
End netlisting Apr 6 23:23:36 2014

The netlist is up to date.
Time taken to compare the design with netlist: 0.0s
...successful.
compose simulator input file...
...successful.
start simulator if needed...
...successful.
simulate...
INFO (ADE-3071): Simulation completed successfully.
reading simulation data...
...successful.
net /in selected but not highlighted
net /out selected but not highlighted

---Any solutions? Thank you!

    Hi,

    From the information given so far, I don't have a specific solution, but I'll try to describe a likely scenario. 

    It sounds to me like you are trying to plot using the Plot Outputs icon on the lower right of the ADE L window, but if you are using a different method, please specify.

    The first thing to check is that the desired signals are actually being saved in the output file.  The easiest way to determine what the simulator is being told to save is to look at the netlist file using Simulate->Netlist->Display.  Near the bottom you want to look for the lines that begin with save and saveOptions.  From the description, I would guess that you have a save statement that does not include your signals "in" and "out".  This could happen for a variety of reasons, but the most common would be that you have the Plot checkbox enabled, but not the Save checkbox for these signals in the Outputs pane.

     Hope this helps.  If not, can you reply with the save and saveOptions lines from the netlist as well as the first setting in the Outputs->Save all... dialog (Select signals to output (save)).

    Regards,

    TOM
