LT Spice annoyance

Started by John Larkin February 26, 2018

I like to have my schematic on the bottom of the screen and waveforms
above. Once in a while, LT Spice elects to swap them. I can't tell why
it does this, or how to make it stop.

Any ideas?

You can float the windows and put them anywhere you like. Cheers Phil Hobbs -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics Briarcliff Manor NY 10510 http://electrooptical.net https://hobbs-eo.com

Sure, but they don't stay where I put them. -- John Larkin Highland Technology, Inc lunatic fringe electronics

Hello John, Make the window active which you want on the top of the screen. Then click on "Window" in the menu-bar. Window -> Tile Horizontally Now this window is on the top and the other is on the bottom. Best regards, Helmut

Hey quick question while you're here if you don't mind! Do any of the current versions of LTSpice leverage multiprocessing or multiple cores when running sims from the command line/shell for e.g. batch runs or Monte Carlo, or is still single-threaded except from the GUI? I can't seem to find any current information about this online

Pretty sure it's multi-core for a few releases now.

Ya when working on a schematic in the GUI editor and running the sim there it is. You can also run the sim without the GUI on a completed schematic file and have it spit results to a log file like you were executing SPICE on an old-timey UNIX mainframe. And I don't know if it leverages multiple cores per terminal-executed process instance in that situation, for some time I know it did not but that was several years ago. I guess I could just look, I'm sure there's some Linux command or program to view per-core processor load but I'm not a *nix expert and don't know it off the top of my head, I should check that

Simulate -> Control panel -> SPICE -> max threads Cheers Phil Hobbs -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics Briarcliff Manor NY 10510 http://electrooptical.net https://hobbs-eo.com

The terminal doesn't have a menu!

Tear a strip off that Domino's menu under your chair and run it through your keypunch machine.
