WebPower Delivery Network (PDN) is one of the most challenging topics in modern VLSI design. Due to aggressive technology node scaling, resistance of back-end-of-line (BEOL) layers … WebExperiments have shown that a 5 percent IR drop on a clock buffer can slow down its speed by up to 15 percent. The reduction in speed is due to two mechanisms as shown in fig 2. First, the IR drop on the power input of inverter1 slows the charging rate of the output. The output voltage of inverter1 rises only up to VDD minus the IR drop. incompatibility\\u0027s kv
