I just joined as I was looking for a cmos logic library for LTSpice XVII. A more general approach to simulating logic IC's is that all logic functions can be (and were) created from 2 or 3-input NAND's although some stuf like 3-state is a small extra step. It is also harder to get analog channel selectors, phase locked loops and such to work this way.
