Hi everybody,

I am a new user of LTSpice.

Looking into the model list I am not
able to find the models for a semiconducor (diffused) resistors and capacitors.
They are not very important but some netlists are using them.
Are these models available in LTSpice? They are standard models in Berkeley Spice3, may be useful to add them for compatibility.


Is there an upper limit for the numeber of components in the standard.*
libraries (diode,resistor,capacitor...)?

Using the .STEP statement it seems difficult to analyze the different waveforms because it is not possible (is it right?) to understand which
value of the parameter is related with a particular waveform. Is there a
way to show which value is used with any waveforms?


Regards

Massimo

You can use the standard resistor and capacitors model
statements. It should be able to understand both
Berkeley and PSpice syntax.

Absolutely not, but there isn't any facility there you
help you organize your models. If you wish, you can
also keep your own libraries separate and include them
by putting a SPICE directive on the schematic of the
form ".lib <filenamepath>"

analyze the different waveforms because it is not
possible (is it right?) to understand which value of
the parameter is related with a particular waveform.

Yes, it can be difficult. You can navigate an
attached
cursor from one dataset to the next with the up/down
keyboard cursor keys.
