Cannot plot transient response (no graph/empty window)

Dear Andrew,

Andrew Beckett said:

By all means please do file a case on that.

I have filed case 46512013 as a minor case to document the issue.

Dear all,

I am someone who is having the same problem as this one.

Could you please let me know if this has been resolved and, if so, how?

Thank you

There are several issues noted in this post (transient response waveforms not appearing in Viva, procuring a license key, updating your version of Cadence), which issue are experiencing?

If it is viewing the transient results, have your tried each of the suggestions in the post? Can you see the signal waveform(s) in the Results Browser? Can you plot the results of a DC analysis? What version of the Cadence tools are you using? What is the data format you are using to save the data? Are you sure the input.scs file contains a save statement for the signals you want to view?

Shawn

My issue is transient response waveforms not appearing in Viva.

1. I can not see the signal waveform in the results browser.

2. I can plot the results of a DC analysis.

3. Version of the Cadence tool which is I using is IC617.

4. I do not use data for simulation. I run the simulation through cadence virtuoso.

    What does the data format mean?

   Fig.1 is schematic of my simulation.

                   (Fig.1 The schematic of my simple circuit, resistance of R0 is 1k)

5. I wrote netlist using cadence virtuoso_schematic. I did not use input.scs file.

Additionally, If I run the transient analysis simulation, The message "No valid waveforms for plotting" appears in the CIW window.

What should I do to solve this problem?

Thank you

Presumably you didn't save the signals in the transient analysis - if this was fundamentally broken, then we'd have many thousands of issues reported about this.

Please provide:

1. The input.scs from your transient simulation of the simple circuit above
2. (optionally) what is shown on the Outputs->Save All form
3. What you see in the results browser - provide a screenshot
4. Which sub-version you're using (you said IC6.1.7 - that's a whole range of releases that might be used - please show the sub-version that's in Help->About or what you get from typing getVersion(t) in the CIW).

1. I did not import any input.scs file (ex. model card) in this simulation.

   Fig.1 is netlist of the simple circuit above.

                        (Fig.1 netlist of the simple circuit above)

2. Outputs ->Save All form is Fig.2

                            (Fig.2 Outputs ->Save All form)

3. What I see in the results browser is Fig.3

                                                                        (Fig.3 What I see in the results browser)

4. Sub-version I am using is IC 6.1.7-64b.500.12 (64-bit addresses).

Thank you

That's not the results browser - I'm asking what you see if you use Tools->Results Browser in ADE. Are you using ADE L here?

Andrew

                                           (Fig.1 What I see if I use tools ->Results Browser in ADE.)

I confused what is results browser, so I uploaded wrong image at Fig.3 of prior reply. Sorry.

I think Fig.1 is a correct screenshot which shows what I see if I use tools ->Results Browser in ADE.

Thank you

yysunj

What is inside the "tran" folder in the results browser? Can you plot any signals from there?

Also - what are your outputs in ADE?

Andrew

V0/PLUS and net2 are inside the "tran" folder in the results browser.

And, my Outputs in ADE is voltage of net2. (red net of below image.)

Finally, this is my simulation ADE screenshot.

Thank you
