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 Alex,

    it depends on what needs altering, but you might do that alteration from within Ocean, for example a design variable (desVar() command) or the simulation temperature (temp() command).  If you are changing the circuit itself then you might be able to use createNetlist() (after you have specified the design using design(library cell view) [insert your actual string values for library etc.]  Ocean uses the 'raw' netlist for the circuit and builds the 'simulation netlist' up around it using the environment you specify with various Ocean commands, whereas the spectre standalone invocation needs the complete netlist which includes the circuit and all of the simulation parameters.  The design() comman can use the path to the 'raw' netlist or the library,cell and view format, in the latter case it can (re)create the circuit netlist as neede, or re-use the existing one.

    I may be a little off here since I don't play with Ocean all too often, but hopefully the above notes are correct and helpful.

    Regards,

    Lawrence.
