This paper describes a new portable test bench for the TileCal sub-detector of the ATLAS experiment at CERN. The system is used for the certification and quality checks of the front-end electronics drawers. It is designed to be an easily upgradable version of the current 10year-old system, able to evaluate the new technologies planned for the upgrade as well as provide new functionality to the present system. It will be used during the long shutdown of the LHC in 2013-14 and during future maintenance periods.
The ATLAS Tile Calorimeter front-end and the back-end electronics use the Agilent HDMP-1032/1034 Transmitter/Receiver chip-set as physical layer. In the back-end is implemented the G-link receiver, the HDMP-1034, which is used to receive and deserialize the data sent by a G-Link transmitter, the HDMP-1032 in the front-end. The emulation of their functionality, in a FPGA, was required to be used in a TileCal front-end electronics tester, called MobiDICK4, implemented at CERN, with future utilization planned for the upgrade of the TileCal electronic system. We have implemented the emulation of the functionality of this chip-set in a Xilinx ML605 board equipped with a Virtex-6 FPGA, around the high-speed serial GTX transceivers embedded in that FPGA. A description of the functionality and the CIMT coding scheme used by this chip-set will be presented. Also, the implementation of our design in the FPGA will be described. Finally, the tests performed, the results and the conclusion about this work will be presented.
