Skew-Tolerant Circuit Design

Circuit Methodology

In this chapter, we will develop a skew-tolerant circuit design methodology. There are many aspects to skew-tolerant circuit design, including the interface of static and domino logic, clocking, and testability. Unless you consider all aspects simultaneously, it is easy to optimize one aspect at the expense of the others, resulting in a system that is slower overall or more difficult to build. Our objective is a coherent approach to combine domino gates, transparent latches, and pulsed latches, while providing simple clocking, easy testability, and robust operation. The guidelines presented are self-consistent and support ...
