Strange LTspice Problem...

I was chasing a similar problem yesterday with the new OSX version of
LTSpice. ASY files don't use the same search path as INC and LIB, which
is a bugger because I don't want my library mixed up in the LTSpice
installed files.

I used the system-call trace program "dtruss" to find all the places
that it's looking for the files. Tried adding a directory under the
installed directory, and was surprised to see that the contents weren't
enumerated, but if the path was used, the files were found. I ended up
making that as a symlink to my library instead (pity you who are on
Windows).

Anyhow, syscall tracing is one way to discover the reasons behind
whatever behaviour you're seeing.

Thanks, Clifford, I'll look into that. I like my symbols and device
libraries separated from my schematics... works extremely well with
PSpice, and I'd like similar behavior with LTspice... this put
everything in one directory is pure crap... _and_ drive-space wasting.

And the ramifications of .INCLUDE, when you have massive libraries, as
I do, is not only extraordinarily bad practice, but it slo-o-o-ows the
simulation.
