Abstract: A method includes receiving at a management component of an FPGA a persona change request and issuing a request by the management component to a reconfigurable PR slot of the FPGA to change a first persona of a first circuit device of the FPGA to a second persona of a second circuit device of the FPGA. The management component, the reconfigurable PR slot, and the first and second circuit devices are configured in the FPGA core. The method includes switching by the reconfigurable PR slot the first persona to the second persona. The method includes issuing a request by the management component, a host re-enumeration of the reconfigurable PR slot, triggering by the host a re-enumeration component a re-enumeration of the reconfigurable PR slot, and exposing by the reconfigurable PR slot the second persona such that the host is reconfigured to recognize the second circuit device.
