In the design of high-frequency electronic devices, crosstalk between Printed Circuit Boards (PCBs) presents a significant issue. With the development of miniaturization and high-density integration of electronic devices, the signal transmission rate and operating frequency of PCBs have significantly increased, making crosstalk a crucial factor affecting signal integrity. Existing research on crosstalk involves various modeling methods and their application in simulating PCB signal integrity; however, current research practices and methods are not yet complete. Despite their high computational complexity, full-wave electromagnetic simulation tools are favored as the simulation tool of choice due to their high accuracy and suitability for high-frequency applications. Therefore, this thesis focuses on modern PCB signal integrity research technology and crosstalk simulation technology, particularly highlighting frequency domain studies based on CST software. The feasibility and advantages and disadvantages of this simulation method are evaluated, and data from physical tests are obtained. By comparing simulation data with actual test data, the discrepancies and possible reasons are analyzed, and the research findings are summarized, pointing out methods for controlling and optimizing PCB crosstalk in higher frequency and more complex environments.
