#86644 - timing diagrams
Responding to: ???'s previous message

My 1st question is that how exactly I may calculate the allowed time delay. I know it has something to do with the timing diagrams, but the calculation procedure is what I don't know.


You really need to draw a timing diagram. Get some graph paper. In a column on the left, write the name of each signal, starting with the first input, and work your way down to the last output, in order.

Then draw all of the inputs. Then figure out the logic and draw the intermediate signals (between latches and buffers, for example), then draw the outputs.

Do it exactly like you'd want to see it in a data book or on a logic analyzer display.
