![]() ![]() asc is (meaning to copy "LTspiceXVII > lib > sym > AutoGenerated/TMK325B7226_MHP.asy" and "JDW_Example_ASC/LTspiceXVII > lib > sym > AutoGenerated/GRM31CR72A105KA01_DC0V_25degC.asy" in the same directory where. include in the schematic), or to just put the. To fix the missing symbols error, you have to either inform LTspice where to look for them (for example by adding an. I don't know where these directories are by default in Mac, in Linux/Wine default installs, the LTspice libs are in ~/Documents/LTspiceXVII/lib/ Copy or symlink there all the files from "former/place/for/MacLTspiceXVII/lib" to "~/Documents/LTspiceXVII/lib/", and it should work. Did the simulation used to work in the former native Mac LTspice install? If yes, then you'll need to copy or to symlink the directory of LTspice libraries from the native LTspice install to the Wine LTspice location for libraries. When I try to open your ASC, there is an error, LTspice "Couldn't find the symbol(s): GRM31CR72A105KA01_DC0V_25deg CTMK325B7226_MHP", which means some libraries are missing. Still haven't figured out how to fix that. Sadly, even with this improved ASC file, the Windoze version of LTSpice still gives me the following error: Unknown sub circuit called in: xu3 n006 n001 0 in 744877004 Where 744877004 is the Wurth coupled inductor in the ASC file required to make the entire power supply simulate. It's a big frustrating problem! As an example, here's a ZIP file containing one of my ASC files with linked Spice models embedded, and with 2 of the required *.asy files which cannot be embedded in the ASC file, so you would need to put those in lib>sym. I just don't have the time to fiddle around with that right now. ![]() While I did install WINE and the Windoze version of LT Spice on it, I've previously spend hours installing many parts into my MacOS install, so none of my ASC files will work in LTSpice for Windows on my iMac without major tweaks. I absolutely HATE running any Windoze apps on my Mac, but per the previous comment here about WINE, that seems to be my ONLY recourse, sadly. Well, only two replies in the LT Spice Group here (I am "James W."), but neither were of any help to resolve the current slowness. Have anybody experienced similar thing? Do you have any idea how can I increase the simulation performance? Thanks, Mate The backside of the Macbook is cold so there is no thermal throttling. I'm using the latest version of the program which is ported to Apple Silicon M1, so it runs natively, however the activity monitor only about 15% processor utilization when I run the simulation. I have to admit that the simulation isn't the most optimized, but it is definitely can be solved. There was no convergence issues, since other two machines could run it perfectly fine, also the Macbook never stuck in a single timestep, however it calculated the timesteps very slowly. The simulation never finished on the Macbook, because I've stopped it after 1.5 hours (around 45% completion). The simulation took about 20 minutes to finish on a Dell XPS 13 (i5-1135G7, 8GB RAM) and about 30 minutes to finish on a desktop PC (i5-6600K, 16GB RAM). I've tried to run an LTSpice simulation on this machine. The developer is very responsive to requests and bug reports, and thus the rather high rating of 4 stars.Hi folks! I've got this new Apple Macbook Air M1 with 8 CPU, 8 GPU cores and 8GB of RAM. That said, it has got a *lot* of potential, and i already like it better than any of the other vector drawing applications available for OS X. I tried his other pure vector editor called "sketch" wich is in beta now, and you can totally tell it shares much of the same code base since it shows signs of pretty much the same bugs as drawit has. I really, really hope this gets fixed in the near future. I would love to buy it, but unfortunately it has got a few unfortunate problems/bugs, that render it unusable IMHO: expose and positioning is excellent addition to this application! The toolbar provides fast access to some useful features. I love how intuitive it is to work with, and the stacked layers in the sidepane makes a lot of sense. It's lightweight, but i had a few performance problems when working with high resolutions. ![]()
