Well, the one i use doesn't do this.  But it's superior to DigSim in all
other respects.  It is: LogiMac, by Chris Dewhurst, $28 from Kinko's
Acedemic Courseware Exchange, 800/235-6919 (CA 800/292-6640).  It's
great, enabling numbering of pins, naming of signals that you want in a
timing diagram, assigning a delay (transition time) to components
(although only 256 levels of resolution), pretty good rubber-banding (in
contrast to DigSim, which lays signals on top of each other), fairly
good generic component library (can approximate most TTL stuff and
more), good page-layout capabilities (prints out multi-page drawings,
showing you page boundaries in a "show page" mode).  I admit i missed
the capability to make components, but i got along.  I think the author
has a more expensive (>$100) version called LogiWorks (604/669-6343)
that is more functional.  But for less than the cost of a textbook, this
one is fine.  I designed the main timing logic section of a digital
sampling oscilloscope using this, and it saved me many hours in the lab.
