This Figure shows a schematic representation of a connection option to connect VCCINT_VCU to ground when moving from an EV device to a CG or EG device. The migration path would be to DNP the VCCINT_VCU regulator and populate the two previously DNP resistors to ground the VCCINT_VCU planelet. To connect to ground (CG/EG devices), populate the resistors on the side with zero ohms. Two resistors are used to minimize inductance and increase current carrying ability.
