Logic gate Simulation Software?

[mishima]

Hi, I have used Digital Works and Logisim for doing things like building memory cells out of logic gates and general study of sequential logic. The free version of Digital Works does not work on my 64 bit windows computer at work, and Logisim does not offer all of the features of Digital Works (timing diagrams, namely). There seem to be a lot of logic gate simulators out there and I was curious if someone might be willing to share their experiences with a good one.

It's been years since I've had access to one I'd trust, but I have used a package called CedarLogic to get me by.
