One of my students just sent me the following related to problems with a MATLAB script we use also not being able to read the output of the newer version of LTspice. This (newer version of LTspice represents characters with 2 bytes instead of 1) is likely the issue with Electric so if someone wants to use the newer version of LTspice with Electric the below might be useful (if you make the programming Java change).
If there is ever a new version of Electric, that is v. 9.08, it would be good to get the LTspice code updated so that newer version of LTspice work with Electric. Again see: http://cmosedu.com/cmos1/ltspice/ltspice_electric.htm Best wishes, Jake. ------------------------------------------------------- Old versions of LTSpice apparently use one byte to represent characters. The old 'readLtsRaw.m' script would therefore use this code to read from the header: header(linenum,charnum)= fread(fid, 1, '*uint8'); The result is that when the new versions of LTSpice use two characters (UTF16?) every second character is just reading a zero and the condition checks for end of line and end of header fail. Changing the code to read two bytes fixes the issue. the corrected line is: header(linenum,charnum)= fread(fid, 1, '*uint16'); Updated 11/22/2020 -- Faculty do research to enhance their teaching in the lab and classroom. http://cmosedu.com/jbaker/jbaker.htm On Saturday, October 10, 2020 at 1:00:50 PM UTC-7 [email protected] wrote: > Very thanks Mr. Steven Rubin for your help with the netlist file concepts. > > Very thanks Dr. Jacob Baker for your proposal, it´s work fine. > > El sábado, 10 de octubre de 2020 a las 15:01:25 UTC-4, rjacobbaker > escribió: > >> When they emailed directly I suggested the following. >> >> By putting the text for the netlist in spice code it should allow running >> it directly with LTspice but I haven't tried it. >> >> ---------------------------------------- >> see: http://cmosedu.com/videos/electric/tutorial1/electric_tutorial_1.htm >> >> and the portion seen below.
