I don't know how ADI views LTspice. It's a free tool that likely provides only a minimum return. Maybe they will find someone else to take it over. Or maybe they will allow it to continue without much further effort. Probably the only real work it requires is to support models for new parts. I'd be willing to bet that is already handled by the groups who produce the various parts. -- Rick C. - Get 1,000 miles of free Supercharging - Tesla referral code - https://ts.la/richard11209

I have found the schematic entry increasingly flakey of late. Put a .param statement or simulation command, .tran, .ac or whatever, on the schematic. Run the sim, then right-click on the command. The dialog box (the new style introduced in XVII) pops up, change some values, hit OK. The command on the sim is unchanged. ctrl+right click and edit the statement directly, if you can remember the syntax, hit OK and the edits succeed. Anybody else seen this?

If you switch from, say, time domain to frequency domain sim, the parameters get all scrambled. I flip the .tran and .ac command lines between directives and comments to change sim mode. It didn't used to be necessary to do that. Maybe Analog wrecked the philosophy. It would be interesting to hear the story some day.

Is it time to have a discussion on "the last stable and nice version"? and get the related install executable stored someplace?

Mike is probably NDA'd, or maybe paid, to not > tell. >Hello John, The "problem" caused when switching between the simulation type while using the standard dialog has been implemented years ago by Mike - an extra editor for every type of command line. There is an easy workaround. Make seperate SPICE-directives for each type of simulation which you need and make all to comments. Then make only the one you need to a SPICE-directive. Another department of Analog Devices supports now LTspice. Earlier or later this would have happened anyway. I am happy that Analog Devices has decided that LTspice is their primary simulation tool. This guarantees that LTspice will be supported for the next decades. Helmut Founder of the LTspice group in groups.io.
