1.4.5.1. General Rules for Capacitor and Power Plane Placement

Follow these rules for placing the capacitor and power plane in an Intel® device:
  • Place each decoupling capacitor in close proximity to the corresponding power plane it decouples, so the capacitor mounting inductance loop is minimized .
  • If possible, place the power and ground planes in close proximity to the FPGA device so they minimize the BGA via inductance loop.
