Automated Decoupling Capacitor Analysis

When working in deep submicron technologies, designers are left with the task of reducing the cost of their design to meet tight design schedules within the provided budget. Optimization of today’s high-volume printed circuit boards and packages is mostly based on different capacitor models, capacitor price and different number of capacitors, and it must be achieved without compromising the design’s signal-and power-integrity performance. This application brief will discuss PI Advisor, an add-on option introduced in ANSYS SIwave, that significantly improves engineering productivity by automating decoupling capacitor selection, placement and optimization for printed circuit boards and packages.
