For timing diagram binary data, allow data to be indetermine

Question

In timing diagrams I may have a binary signal that can be at either a logical high or low value, but at some point in time it is indeterminate between just those two states. I should be able to show that as a {0,1} like I would with a robust signal.

Yes, that's what I am looking for.

Answer 2

I would also need the same thing. Concise signals are not the only ones that can be undeterminate. Binary could also be.
