Power integrity simulation and design optimization of the circuit

Power Integrity (PI) issues with the development of high-speed digital circuits, simulation is the best way to solve it. In this paper, the HyperLynx simulation software is used in the PCB design process, in order to optimize the schematic diagram design and guide the PCB layout and wiring. The method of verifying the correctness of PCB design in the simulation after wiring is also introduced. In the process of simulation, combined with the relevant theory of PI, according to the simulation results, the method of optimizing circuit design is proposed, and the simulation waveform is verified. The results show that PI simulation in PCB design is of great significance to improve PCB design quality.
