Testing and firmware development for the ATLAS IBL BOC prototype

For the coming upgrade pixel detector of the ATLAS experiment at the Large Hadron Collider a redesign of the current data readout is necessary. To communicate with the additional 448 front-end chips assembled in the Insertable B-Layer (IBL) new FPGA based readout cards consisting of a Back of Crate card (BOC) and a Read Out Driver (ROD) have been developed. This paper describes the firmware and hardware development of the new BOC prototype. Firmware tests, like electrical and optical loopback and communication tests with the new IBL front-end modules and the ROD will also be presented.
