WebJul 15, 2024 · There could occur IR drop in your power delivery network which may lead to variation in available voltage to operate a cell. Power comes from the power pads/ Bumps and distributed to all standard cells inside the chip through the metal stripes and rails which is collectively called the power delivery network (PDN) or power grid. WebMar 23, 2024 · It becomes very important to limit the IR drop as it affects the speed of the cells and overall performance of the chip. There are two types of IR drops: Static; Dynamic; Static IR Drop: Static IR drop is an average voltage drop for the design. It is dependent on the RC of the power grid connecting the power supply to the respective standard cells.
