Overview
Combinational circuits lack the ability to store information. For this purpose, latches and registersare introduced. At a first glance, they are simple circuits consisting of a few gates only, Their distinguishing feature is a feedback loop. It makes the analysis of the circuit much more subtle and critical, and gate propagation delays play a crucial role. Our advice is therefore to restrict circuit design to combinational circuits, and to acquire latches and registers as complete parts. Feedback loops then exist only within these parts.
