The increasing complexity of nowadays wireless RF devices increases the demand for accurate and efficient simulations of large and complex PCB designs. Identifying and predicting potential issues early in the design process saves resources, time, and money. SIwave helps you model, simulate and validate high-speed channels and complete power delivery systems typical in modern high-performance electronics. It accurately extracts multi-gigabit SERDES and memory buses, providing product sign-off compliance for various designs.
This blog describes how to correct, assign, and define components in your board using ANSYS SIwave. It also shows how to define components to terminate traces to enable the usage of the ANSYS SIwizard. The SIwizard, provide an automated way to setup signal integrity simulation of electronics circuits and PCBs. However, the wizard doesn’t consider open or unterminated traces.
