I don't use LTspice a lot how ever, recently I have been poking around
with a simple buck circuit that just does not seem to do in spice as it
does in real life. I can put those little things aside how ever, I do
have a problem when changing values and then exec the sim. It pops up
with an error stating something on the line of
"Step size to small x.xxxxxx xxxxxx, error at NC_01"
that may not be the exact message but it's close..
This can happen just about any where on any component I change the
value on. To fix the problem, I decreas/increase the value by 1.
For example:
If change an inductor to 150uf, it didn't like that. I could
go larger or smaller, but I found that all I needed to do was to
add 1 or subtract 1 to make the sim happy.
This does not happen in just inductors, it happens with R's caps
etc..
Any one have something on that?
