Ngspice raw file output question Hi all I m trying to use the r flag in ngspice batch mode to specify a raw file to output the simulation results to The thing is that although ngspice clearly acknowledges the path and file name I specify on the command line because it prints a message to the console detailing it as the binary raw file to output to it doesn t ever actually write a file Can anyone help Thanks

Thanks < Amro Tork> I can get it to you later

If the file is not written it is probably because simulation was not started If using ngspice in batch mode do not use ` control endc` constructs write the simulation commands in the old legacy spice way ` option savecurrents` ` tran `

also look at the `out` file generated by ngspice in the directory ngspice is running Warning and error messages go there

That s interesting < Stephen Schippers> but I run in batch mode all the time now using control and my simulations always run fine but they only write to raw files when I explicitly use the write command from within control

Stefan Schippers · Answer

< Tom> you are right even in batch mode ngspice runs simulation specified in a control block however no raw file is produced even if r xxx raw is given If you remove the control endc and write a plain tran or dc or ac line then the raw file is generated I use this command in general `ngspice b r rawfile raw o outfile out circuit spice`

Thank you very much < Stefan Schippers> I will try that this evening
