Asynchronous Circuit Design

This is very similar to Synchronous Circuit Design, but there are some added complexities due to the fact that it is asynchronous.

Since it is asynchronous, we don’t have the clocks so it is hard to define the transition from $Q_t$ to $Q_{t+1}$. We also don’t have Flip-Flops, which depend on Clock Signals to transition.

Two changes in one step is not possible,
