74xx series TTL library avaliable?

Is there a lib like this out there? I want to simulate some older
designs to get my head around certian functions, and a lib like this
would be very beneficial.

Thanks for any info,

You could probably write a library in an hour or two. You won't need to do
the whole TTL data book, chances are you'll only need a handful of models.
You'll need to find a copy of the TTL databook somewhere.
 
Yeah but that requires work. :) Anyways I figured by now there must
be a lib out there somewhere.

At one time 7400 TTL libraries were common but that was a long time ago.
The amount of work involved is really trivial, the 7400 series components
can each be described in a few lines of Verilog.
 
Free Model Foundry has a 74/54xx model library that has full timing,
etc.

I could only find VHDL models on the FMF site for 74xx parts. Good
enough for mixed-language simulation, but if the O.P. wanted Verilog
models he may find some translation work necessary...

I assumed that if the OP posted this in comp.lang.vhdl, which he did,
then vhdl models were acceptable.

I'd hate to try to translate a VITAL vhdl model into verilog!
