It is required to connect the VCCSDFEC rail to the plane that contains VCCBRAM. VCCSDFEC and VCCBRAM should have separate planes under the RFSoC, which are then merged when outside of the RFSoC shadow. This Figure shows the recommended plane methodology. Decoupling capacitors for the VCCSDFEC are described in PCB Decoupling Recommendations.
