Norbert, You can run a netlist in batch mode like this: scad3.exe -b myfilename.cir The waveform data will be in the file myfilename.raw and the .log file will be in the file myfilename.log. --Mike

Norbert, Not at this time, but the request comes up now and again, so I'll add it when I have time. --Mike __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier.

Does anybody have suggestions of how to use LTSpice in a 'batch' way, either from Windows or from Linux? I want to write a program loop to build an input netlist file, submit it to LTSpice as a batch

Some Spices print out a table of device operating point information (e.g. device gm , gds, capacitances) for things like mosfets and bipolar devices. Is this available in LTSpice? Regards, Norbert.

Bernhard, The power rating is only used for the Bill of Material. You can ignore it as LTspice otherwise does. Note you don't have to use that editor to change the value either, just move the mouse to

Hello, Thank You very much, Helmut. Your help was helpful! I now can use the TL071-OpAmp in my circuits - perfect. But one thing astonished me: As I changed the value of a resistor, I saw that it is

Mike, I'm thankful for your promptness. This is GREAT customer service! Andrew McClelland P.S. I'm interested in integrating this with other tools like VIPEC (an S-chart analyser) or GEDA (GNU pc

Andrew, Thanks for reporting the problem. The crash mode was inadvertently introduced on Sept 15 of last year while trapping a different problem. I'll put up an update next week to take care of that

I ran a sim with start time=0 and zoomed in on a portion of the waveforms near the end of the sim. I then re-ran the sim with Tstart and Tstop specified as the beginning and end, respectively, of the

Norbert, Oh, yes, now I see what you're trying to do. Yes, the only supported way you have to scope math to an instance is with a subcircuit. (LTspice can scope math to a symbol when used to read

Mike, It does help to see the schematics! Please take a look at twomos.asc and twonorbs.asc, and how the parameterization works, and how AD is calculated as an example. In twomos.asc, the L and W of
