Prometeo Workshop on Front-end electronics for gamma and complementary detector systems 17 th -18 th November 2011 – IFIC (Valencia) Diego Barrientos

 Introduction  Firmware development  Simulation  Hardware testbench  Software development  Results  Conclusions and further work

 Large projects with high-speed data rates  Several complex electronic devices  Definition of the electronic boards in the system  Initialization with register values or procedures  Storing configuration parameters for backup  Monitoring some key parameters  Handling error/alarm events and notifying them  Acceptance of simple commands for control

 One optical lane but multiple buses/registers  Multi-Gigabit Transceivers ◦ 8B/10B encoding ◦ Control messages, data flow ◦ Error handling  Custom protocol ◦ Xilinx RocketIO ◦ Aurora

 Virtex-4 ML423 Ev. Board  Virtex-5 ML507 Ev. Board  1 st test: Virtex-4 loopback (Switches & LEDs)  2 nd test: Virtex-4/Virtex-5 (Switches & LEDs)  Final test: Virtex-4/Virtex-5 (I 2 C device)

 Virtex-5 PowerPC  Integrated peripheral: ◦ RS232-UART ◦ Switches/LEDs ◦ Slow control interface  C functions developed

 Slow control interface for the new AGATA digitizers  Mirror registers synchronized through serial link  Firmware validation with Xilinx Ev. Boards  Incoming prototypes for the new preprocessing and digitizer electronics  Design and validation of the digitizer’s control card  Firmware integration in the whole system
