Power Integrity

The main goal of power integrity analysis is to be able to provide clean power to the chip circuitry and to eliminate the effects of power supply noise on the chip's output signals. When power noise has an effect on the chip, it can cause logic errors in the output signals or create timing problems. In addition, the power ground network and the signal network are not severed, but tightly coupled together. So the power ground noise will also be coupled to the surrounding signal lines through capacitive or inductive coupling, or radiated to the outside space, which will produce complex EMI, EMC problems, resulting in product EMC testing does not meet the standards.
