How to deposit simulation result into a file?

Alex Liao

Hi, I am wondering is there a way to save an output into a file, like a .txt which it is easy to read from.

 

Specifically, in the "Setting outputs" of Virtuoso Analog Design Environment (ADE) I have: 

Name: PhaseMargin

Expression: (phaseMargin((VF("/Vout") / (VF("/Vin+") - VF("/Vin-")))) + 180)

 

After simulation, I got 80 degree displayed.

But is there a way to save this '80' into a .txt file?

I am using SpectreS as the simulator. I think there are some commands to output results.

 

Any answer is appreciated.

Thanks,

Alex

  • Hi Lawrence,

     

    Thanks for your quick response.

     I did the experiment and got an desired output.

    What I did is just to use ADE to do the simulation and to save the ocean script. After that I open the saved script and add the ocnPrint() function.

    When I opened the saved ocean script, I found it mimiced the action of simulation by having a "run()". I think it relates to the run_simulation command which is "spectre + escchars + log ../psf/spectre.out -env artist5.1.0 -format psfbin -raw ../psf -E -cols 80 raw/Mydesign". 

     I am curious about the different of run_simulation between using spectre command and using ocean script. I have to know how does the “ocean script version of run()” relate to the circuit_netlist.

     In my work, I need to vary the netlist and send the modified netlist back to re-run the simulation and get data from, maybe ocnPrint(). It looks like an loop. All the process are executed by code without interference with GUI. Therefore, I want to know how to make modified netlist work or refected in "run()" or maybe other ocean scripts, which are responsible for run_simulation purpose.
