UltraScale Architecture Clocking Resources User Guide
www.xilinx.comaddition, there is a local BUFCE_LEAF clock buffer for driving leaf clocks from horizontal distribution to various blocks in the device. BUFGCTRL has derivative software representations of types BUFGMUX, BUFGMU X1, BUFGMUX_CTRL, and BUFGCE_1. BUFGCE is for glitchless clock gating and has software derivative BUFG (BUFGCE with clock enable tied ...
Lecture 7: Power
user.engineering.uiowa.eduClock Gating The best way to reduce the activity is to turn off the clock to registers in unused blocks – Saves clock activity (α = 1) – Eliminates all switching activity in the block – Requires determining if block will be used . 7: Power CMOS VLSI Design 4th Ed. 18 Capacitance ...
