Overview of SI/PI Simulation

Signal Integrity (SI) and Power Integrity (PI) are two critical factors that must be ensured in today's high-speed electronic product systems and PCB designs. SI/PI directly determine the quality of system signals and power, thereby affecting correct data transmission and system bit error rate. To evaluate and simulate SI/PI during the design phase, professional EDA tools are required for simulation analysis.

The accuracy of SI/PI simulation analysis and its correlation with actual test results depend on the accuracy of the simulation models themselves on one hand, and on the correctness of the simulation methods and the experience of the simulation designer on the other hand.

Xinmai possesses a team of experienced SI/PI simulation engineers, a simulation model library validated by actual tests, mature design experience, and successful case studies. This enables us to help clients quickly resolve SI/PI issues during the design and testing phases.
