Asynchronous circuit design

MohamedMohie

Hello experts,


I need your help in this, though it may sound basic:

I'm designing a simple asynchronous circuit by building two 4*1 Multiplexers followed by a 2*1 MUX with enable signal.

I need to sense when the first two 4*1 MUXs finish their job to fire two signals that when AND with each other, they activate the "enable" signal for the following 2*1 MUX to proceed. But the problem is, I don't know how to implement such circuit that detect when the 4*1 MUXs finish their job in order to enable the next 2*1 MUX .. or If there are other mechanisms to detect the completion.

I'm very new to asynchronous design so pardon me if my question looks very basic to you.

I really appreciate your help.

Thank you
