I've not found an ideal option for resistors, capacitors, standard package
inductors, etc. Usually I add those attributes at the schematic level
rather than the library level -- this still generates perfect BOMs and
supports copy & paste, etc. One thing I do sometimes is make a
kind-of-library-thing (for want of a better name) which is essentially a
schematic containing a large number of circuit snippets that I can cut &
paste into a working design. Used with an underlying library this serves a
similar purpose, but deals with the resistor/capacitor issue and also of
course lets you make a library of subcircuits rather than simply devices.
In reply to Charlie Wallace, the Octopart add-in is here:
I don't know if it works on anything other than for-real Excel on Windows,
since that's the only thing I've used it on, but it certainly works
I second the BSDL ULP for making parts that can be hacked on further -- I
often use this to make packages. It does work without a BSDL file,
incidentally, though if you actually have one it is a lot easier to use.
I've done a 484 pin FPGA package from a BSDL generated directly from the
Actel chip editor software before, which worked fine and saved many hours
