如下图所示,该ICG单元就是一个pre-conctrolled negative-edge triggered clock gating latch。 -control_point none | before | after对于DFT测试电路,为了满足电路可控,需要引入TE信号来控制latch的使能端。before就是在Latch之前插入或门,将TE信号和时钟使能信号或起来然后连接到Latch的D端。同理,after就是在Latch之...
set_clock_gating_style是一种用于时钟门控的技术,它可以根据特定需求来控制时钟信号的输出,从而降低功耗和提高性能。 二、set_clock_gating技术的原理 set_clock_gating技术通过在不需要时钟信号时关闭时钟门,以减少时钟信号的输出,从而达到降低功耗的目的。这种技术通常应用于需要周期性唤醒和睡眠的设备,如移动设备、...
aThe architecture team and RTL design team should have the same set of design rules in the product development. For example, the clock gating rules, the power gating rules, the rules on the use of reset, the sequential coding style (behavior based vs. structure macro based.) 建筑学队和RTL...
