5.1. PDN Design Guideline for Unused E-Tile
All E-Tile power rails (ending with _GXE) must be powered on PCB even if the E-Tile is not used in your board design. However, due to only small static/bypass current usage, the recommended decoupling capacitors in Table 13 for E-Tile power rails in this document are not required on PCB. You must still meet the voltage specification at package pin for the E-Tile power rails by selecting a proper voltage regulator (such as low ripple, DC setpoint, recommended VR bulk capacitors, etc) and considering the static/bypass current.
