· 脚本中使用hookup_power_gating_ports命令来自动插入power_pin[1-5]端口和层次模块的引脚。同类功耗引脚的端口或引脚会被连接在一起。例如属性同为“power_pin_1”的引脚将被连接在一起,其默认名为“power_pin_1"。下图为执行hookup_power_gating_ports命令后设计中插入端口和层次模块的引脚。我们可以使用选项...
时钟门控,即clock gating,其核心理念在于通过控制时钟信号,以实现对芯片上部分功能的功率节省。当芯片的某部分功能在短时间内无需运行时,关闭这部分的功能时钟,即可达到降低功耗的目的。这一技术被广泛应用于低功耗设计中,其作用机制在于通过逻辑单元的额外引入、优化时钟树结构等方法,实现对电能的有效...
clock gating时钟门控;门控时钟;时脉闸控 power gating电源门控;功率门控;功率门限 门控时钟(英语:Clockgating),“门控”是指一个时钟信号与另外一个非时钟信号作逻辑输出的时钟。 例如,用一个控制信号 “与” 一个clk,可以控制clk的起作用时间。
Clock Gating and Power Gating are two most commonly used design methods to save dynamic and leakage power respectively. How about integrating the two solutions such that they complement each other? In this post, I will talk about a simple way to do so. Clock Gating is accomplished by using ...

Clock Gating and Power Gating are two of the most effective techniques that are applied today for reducing dynamic and leakage power, respectively, in digital CMOS circuits. The combined use of the two solutions, however, poses some challenges in terms of practical integration of the required cont...
ICG(integrated clock gating):将clock gating cell做成一个大的集成cell,内部一般包括去抖动latch,gating cell(AND/OR),和使能控制单元。 02 — Clock Gating的优点和Metric定义 节省功耗:clock network上toggle减小可以显著降低 dynamic power,同时register的clk pin的toggle可以降低register的internal power。
