组合逻辑没有反馈，电路的输出只与现时的输入有关。而时序逻辑电路有反馈，其输出不但与现实的输入有关，还与原来的输出状态有关，也就是有记忆功能了。
Having had a good review of digital circuit design in the previous chapter, it is time for us to pick up hardware design language (HDL) coding [11鈥 17]. A digital system is primarily a combination of combinational and sequential circuits put together in any mix. To start with, we will...

Having examined the behavior of some of these sub-circuits (both combinational and sequential) in detail earlier, we now examine their hierarchical combinations, as in real-world systems. All sequential circuits are clocked, while no combinational circuit is clocked. The integration of these two ...

and it is easy to compute its impact on the switching of the clock net by using combinational switching activity propagation techniques. However, sequential clock gating alters the sequential nature of the design. For example, to perform observability-based clock gating for the circuit shown in Fig...
Low power test is taking center stage for both combinational and sequential circuits in recent years due to its impact on overall yield. This paper proposes a technique that targets the reduction of peak current during combinational circuit test to realize peak power reduction. Unlike previous ...
