Yes, there is a simple fix that allows reliable operation with
real-world cmos schmitts. It's sort of obvious.

If you think so build and test it, or SPICE it. Show us the results.

Hell, I've already done the only circuit that really works.

My circuit doesn't work? Sure it does. I captures the first
transition just as requested by the OP.

And includes the unobtainium "Delay" box, whose output splits into two
timing-critical paths, always an alarm in async logic. Finish the
design and we'll see.



Playing with circuits is no fun when the other guys just play couch
potato.

Oh, Dear John, You've become a smug SOB on a level with Bloggs ;-)

Blogs doesn't design electronics. Surprisingly few S.E.D posters
actually do.
