Another problem with the LTspice Help, is that just about everything
starts with the old non-graphical input format of traditional (i.e.
Berkeley) SPICE:
Syntax: Sxxx n1 n2 nc+ nc- <model> [on,off]
Example:
S1 out 0 in 0 MySwitch
.model MySwitch SW(Ron=.1 Roff=1Meg Vt=0 Vh=-.5 Lser=10n Vser=.6)
And then we tell everyone to use the schematic editor, and upload
schematic files instead of netlists.
So the Help file is a little like using DOS in a Windows world.
Plus the references to a SPICE "deck", a model "card", etc. Imagine
if the Help for MS-Windows gave everything in terms of DOS commands
and command-line switches.
It probably makes little sense to anyone coming to LTspice for the first time.
For those of us who used SPICE before, the relationship between the
element and the model, by way of the model name, was obvious. And we
take for granted that the element is now a schematic symbol, but the
model is a "SPICE directive" ... which is mentioned in the Help
description but not really explained.
So yes, there are lots of problems.
