Hi all,

I am looking for some information on adding logic gates to ltspice. I just need some 2 input standard logic gates, AND, OR etc, I have read that there are some available at the ltspice yahoo group, which I joined... but I am unable to find the right files I need.. does anyone know where the files are located, or at least how they are named?

Thanks in advance

What do these files have that the standard files do not? Have they been modified to mimic actual parts for example?
