Strange LTspice Problem

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.

Clifford Heath. 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. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.
