[time-nuts] Using CPLD/FPGA or similar for frequency

This thread really makes me want to do an FPGA timing project. I have a

Papilio One on hand, which uses the Spartan 3E.

But what to do with it? It has to be something much more interesting than

what a PicDiv or simple logic can do to make it worth my time. Hmm...

How about a 1pS resolution TIC? :)

Or a >12 digit frequency counter? :) :)

It's not a proper time-nut project unless there's a nutty element...
