1 Tuesday September 18thCALICE_meeting @ Cambridge1 GDCC “next replacement of the LDA” Franck GASTALDI

2 Tuesday September 18thCALICE_meeting @ Cambridge2 Outline Overview of the DAQ The story of the LDA –The Firmware –The Board –Feedback after the last test beam The GDCC project –Status of the current work –Planning Conclusion

3 Tuesday September 18thCALICE_meeting @ Cambridge3 Overview Machine clock 5 MHz DIFsASUs DAQ2 PC DCC Clock & Control Digital (Config, Control, Data, Trigger, Busy) over HDMI Clock & Trig, Busy over HDMI LDA Ethernet network card LDA DCC ×10 ⋮ ×9 Optique GigE Debug USB.... External Trigger DCC = Data Concentrator Card CCC = Clock & Control Card LDA = Link Data Agregator DIF = Detector Interface

4 Tuesday September 18thCALICE_meeting @ Cambridge4 The story of the LDA

5 Tuesday September 18thCALICE_meeting @ Cambridge5 The Firmware Xilinx IP GEMAC Several state machines to manage and extract datas from and to the DIFs DIFs Links From LDA (contain ser-des, 8b/10b Block, protocol management for the DIF packets) Ethernet CCC interface LDA is divided in 4 main functions Ethernet interface : Xilinx specific, black box for the user and cannot be maintained. Intermediate interface : Packets manager, can be re-used, but difficulty to do the reverse engineering. DIFs interface : Protocol & Link management, “good enough” knowledge of code for re- use… but need for improvement for the next FPGA family. CCC interface : Distribution of clock and trigger, detection of busy, RamFull, selection of some fast_commands To DIF

6 Tuesday September 18thCALICE_meeting @ Cambridge6 The Board LDA is a board with several mezzanines –Clock connection from the CCC –Ethernet connection –HDMI connection

7 Tuesday September 18thCALICE_meeting @ Cambridge7 LDA on experimental site example for DHCAL Rails have been installed to maintain the LDA example for ECAL Put up on the chassis

8 Tuesday September 18thCALICE_meeting @ Cambridge8 Feedback after the last test beam and our experience of this board The board : –Not a standard size format –Problem with the grounding and shielding –Only few channels works correctly on each board (difference from a board to another one) The firmware : –GEMAC Xilinx IP core obsolete Mandatory to use the old Xilinx software ISE11 –Difficulty to maintain the main part of firmware

9 Tuesday September 18thCALICE_meeting @ Cambridge9 Towards a new board The GDCC (prototyping step)

10 Tuesday September 18thCALICE_meeting @ Cambridge10 GDCC firmware Gemac lithe Homemade (from xilinx reference design) Totally free Some parts from LDA & DCC Main Interface With some modifications and improvements DIFs Links From LDA (With improvements in the future) Ethernet TODIFTODIF CCC interface We do not change the main architecture compared with the LDA. Only the code is slightly modified. Re-using some blocks from LDA and DCC Replace the GEMAC IP core by a free module with the same behavior Replace some blocks for an easiest maintenance and future evolution CCC function manages the fast command and busy, clock and trigger are managed by the hardware

11 Tuesday September 18thCALICE_meeting @ Cambridge11 Firmware architecture (In work) GMAC Stream “Homemade” RX arbiter TX arbiter GDCC packet DIF Data pkt Fast CMD pkt DIF Interface Module (ser-des, 8b/10b) pkt wrapper Others pkt (udp,…) Optional, in preparation Internal register Data buffer to DIF module Data buffer from DIF module GDCC data generator for tests Upstream connection Downstream connection Loopback connection Re-used from LDA and DCC Must be simulated and tested on board Control connection In work

12 Tuesday September 18thCALICE_meeting @ Cambridge12 Firmware tests The firmware is tested on Xilinx Spartan 6 evaluation board. Setup put in place since June Commands have been received correctly The link to the DIF is locked The status can be read

13 Tuesday September 18thCALICE_meeting @ Cambridge13 GDCC hardware architecture Spartan 6 XC6SLX75 VME Multidrop Jtag device (SCANSTA112) USB2 (FTDI2232) Fiber or copper Gigabit Ethernet (Marvell 88E111 ) DDR2 - SDRAM (Micron DDR2 MT47H64M16) HDMI Connection on mezzanine Board DIF & CCC SAMTECCONNECTORSAMTECCONNECTOR FMC connector (type LPC for mezzanine) GDCC is powered by VME connector Dark blue : design based on LDA and DCC but with a reliable connection for the mezzanine. Clock and trigger are distributed by the mezzanine. Light blue : Physical layer device for Ethernet connection Red : new part, foreseen but optional VME : minimum access foreseen (8 bits data, 16 bits address, 1 IRQ, no arbitration) Jtag device for download FPGA : multidrop Jtag access (foreseen to access several boards in remote and the ability to remove a board from the system and retain access to the remaining boards). FMC connector : possibility to connect mezzanine board with FMC standard DDR2 nota : USB device can be used to download the FPGA

14 Tuesday September 18thCALICE_meeting @ Cambridge14 GDCC Board integration VME rail Samtec connector J1 connector HDMI Ethernet & usb SEAM series SEAF series Design of a board with a VME size : Board to board solution FMC connector

15 Tuesday September 18thCALICE_meeting @ Cambridge15 GDCC Layout Mezzanine 12 layers Size : 233 x 52.8 mm Thickness : 1.81 mm GDCC 12 layers Size : 233 x 106.66 mm Thickness : 1.81 mm DIF HDMI * 6 CCC HDMI Additional Samtec connector Foreseen to plug mini-mezzanine board and to test different kind of connectors

16 Tuesday September 18thCALICE_meeting @ Cambridge16 Cost estimation (for 3 boards : prototype part) Estimated time of manufacture : 20 days for the PCB, 5 days for the cabling, 20 days for supplying of components. The production of prototypes takes 2 months maximum –Per board (GDCC main) Board :430 € Cabling : 600 € Tools : 310 € Component : ~293 € Total : 1633 € –Per board (mezzanine) Board : 385 € Cabling : 465€ Tools : 310 € Component : ~178 € Total : 1338 € TOTAL GDCC : 2971 € /board

17 Tuesday September 18thCALICE_meeting @ Cambridge17 Conclusion 3 boards will be launch in production this week –We hope to receive the boards in November Tests will be organized in several steps –Check the hardware part : FPGA download, clock and trigger distribution, etc… –Firmware tests in LDA mode Long term tests –Tests of USB and Jtag devices –Less priority : VME, DDR2 (no written vhdl code for now) GDCC will not available before April 2013 –If there is not a significant problem
