Complex, densely populated designs with multiple power planes and critical high-speed signals are becoming the norm. As this complexity continues to increase, it is imperative to analyze signal integrity (SI) and power integrity (PI) to improve signal quality and guarantee performance. In an ideal environment, SI and PI experts would perform a comprehensive analysis, but this collaboration is often streamlined to adhere to project timelines and budgets. In-design analysis in OrCAD allows electrical engineers and PCB designers to analyze impedance and coupling directly on the PCB canvas without being an SI expert. With in-design analysis, users can find and fix errors during the design when change is easiest with color-coded visual overlays as well as tabular results, allowing the SI and PI experts to focus on the more complex signal and power integrity concerns.
