Is the file really called "MYLIBRARY1.LIB" or "MYLIBRARY1.LIB.txt"? I turn off "Hide file extension for known file types" in Explorer=>Tools=>Folder Options=>View "MYLIBRARY1.LIB" needs to be the full

OK where did I go wrong, I'm getting - Could not open include file "MYLIBRARY1.LIB" I copied the switch out of help, and the library is in the sub directory. MYLIBRARY1.lib *SYM=CSW .MODEL CSWITCH1 1

I recently discovered LTSpice and I love the program. My question is the following: I wish to modify the model parameters of say, the NPN bipolar transistor, so as to see the impact of various

You can do this if the symbol is modeled with a subcircuit. It's described in one of the downloads of this group and now also in the help section Schematic Capture=>Creating New Symbols=>Adding

I need a method to bind schematics to cell and block symbols that uses the symbol attributes, so that instantiating and placing a symbol causes that symbol's definition to be included as a subcircuit

Spectrum Software (makers of MicroCap) has an application note concerning gas tubes at http://www.spectrum-soft.com/news/winter99/sparkgap.shtm While the syntax might be different from LTSpice, the

Helmut, The tolerances that are typically most useful to loosen are abstol, vntol, and chgtol. If you loosen reltol, it's best not to loosed it too much. The "No Bypass" check box is also often an

Reiner, I got the same or similar error message, when I tried to simulate a square-root circuit model. Of course, it is a big different between applications, but maybe good to know, why happened it.

Mike, thanks, for the quick answer! I played a little around and I was able to complete simulate the circuit. The wave-results are not as I wanted and I think I need a lot more simulations until my

I have no experience with Spice and what I know comes from the help file and the previous posts. I guess we all have to start somewhere. What I wanted to do was call up a model from a sidac library

Thanks again to Helmut and Peter. My digital design works now very well, with "real world" parameters. Christian

Rainer, It means the solver failed to converge for the circuit. Usually you have to change some aspect of the circuit to get it to run right. The 1533 is pretty complicated since it controls the slew

Hallo, I'm using scad3 for a few weeks and I'm very happy about the power and speed of simulation. Now, I tried a more complex simualtion with a LT1533 (I modified the sample) and got the following
