Execute .meas file
开云体育
I have several worst-case analysis models that take at least several minutes to run (8, 9, + variables). I’d like to run the meas scripts to extract different sets of measurements, drawn from one Run. At least in XVII, the Execute script command is only under the File menu on the Plot page… ? Thanks, Dave ? ? |
开云体育Thanks, Andy! ?
But if I rename that with a different extension, it still runs the script. In the Help. there’s a hint that it can also derive data from the Plot.
That would load everything back into memory. ? ? From: [email protected] <[email protected]>

I would not think you need any temporary files.? I could be wrong, but I think you need only the .MEAS script files themselves, and of course the .RAW output file. ?
If you come back to a previously run simulation and want to examine the results without re-running the simulation, use Right-click > View > Visible Traces.? That loads the .RAW file back into LTspice and you should be back to where you were when the simulation completed.? I'm assuming that would be all you need to do before executing .MEAS scripts. ? The alternative to Right-click is: View (menu bar) > Visible Traces.? The hotkeys are Alt-V-V (in older LTspice versions). ? Andy ? |
开云体育I closed LTspice along with the schematic, then opened just the sch. View, either by right-clicking the schematic, or from the View menu option, has Visible Traces grayed out until a Run. ? I haven’t yet tried opening a RAW file directly. That’s next… ? From: [email protected] <[email protected]>

You can also open a .RAW file directly into LTspice, and see all your waveforms, and maybe run .MEAS scripts.? But doing it that way, they won't be associated with a schematic.? To re-establish the ability to click on schematic nets to see waveforms, you have to open the schematic first, then View > Visible Traces. ?

开云体育To follow up, loading a .raw file directly then works to execute .meas files. So, answering my original question, after a complete Run, save (in Settings) the raw file(s), or make a copy, while the simulation is still in the app, Reloading that .raw file gives access to the large data from a long and multipart simulation. ?
