L1Calo Status Report 15 October 2015Ian Brawn, on behalf of L1Calo1

eFEX Sent to manufacture 24/7/15 –Bare board (for impedance testing) expected ~today –Assembled module expected 30th October Firmware –All IBERT cores generated –Control FPGA–FPGA interface in development  All L1Calo modules –IPBus Common Register definition proposed at L1Calo Weekly meeting Incorporating feedback 15 October 2015Ian Brawn, on behalf of L1Calo2 Simulation results from HyperLynx for typical track, attenuation vs. frequency eFEX layout

jFEX Simplified board design –Eliminated Merger FPGA –Control  mezzanine –Modular design for Mpod + Processor FPGA “blocks” Time reduction in board design Schematics almost finished; layout ongoing On schedule for Q manufacture 3D model of fibre routing developed –Working on problems exposed at Join meeting Firmware in development 15 October 2015Ian Brawn, on behalf of L1Calo3

gFEX Prototype 1a, no. 1 & 2: –Without/with Proc FPGA (XC7VX550T) –Power, clock & Zynq commissioned –MGTs: 12.8 Gb/s, BER <1.2  GTH (pFPGA)+ 16 GTX (Zynz) simultaneously Prototype 1b –Re-work (CDC->SiLab clock, DDR3, PHY) –  Manufacture 24 Sept Prototype 2b: Full prototype –Design changes 4  V7 → 3  Ultrascale (XCVU160) Redundant readout via Hub-ROD removed (readout via FELIX) –  Manufacture end of year –Routing well advanced Firmware –Control –Test engines –Algorithmic –GBT & TTC interfaces 15 October 2015Ian Brawn, on behalf of L1Calo4 gFEX Prototype 1a, no. 2 Done IBERT eye for pFPGA → Fibre →p 12.8 Gb/s

L1Topo Expect only minor changes to Topo required at Phase-I –Mezzanine upgrade for readout via 2  L1Calo Hub- RODs But… also plan to implement Phase-II requirements at Phase-I –Real-time RoI outputs Associated with L1As Need to evaluate (for Phase II) –Scale of required changes –Optimum system architecture –L1Topo upgrade plan Currently, L1Topo effort bound up in Run October 2015Ian Brawn, on behalf of L1Calo5 Run-2 L1Topo

ROD Initial layout completed in July Power-supply issue : –Switching noise from GE modules few x 10 mV –Solution: ferrite inductors & isolated ground planes PCB manufacture underway Quotes for assembly collected Fully assembled module expected end of November Firmware –First draft of firmware specification circulated within L1Calo 15 October 2015Ian Brawn, on behalf of L1Calo6 ROD prototype, 3D model Power-Supply Test Board

Hub Delicate design process required at the ROD/Hub interface –Tight space limitations after making space for ROD –FEX data fidelity to ROD remains the driving design philosophy Layout and routing underway Assembled modules anticipated mid December – early January. TTC SFP+ connector removed from design. –All optical I/O will be performed via minipod Firmware design progressing in parallel to board design. 15 October 2015Ian Brawn, on behalf of L1Calo7 Hub Layout

FOX Design and production of demonstrator complete: –Lar/TileFOX Demonstrator –e/j/gFOX Demonstrator 2U boxes with –MTP connectors –fanout cables, –Internal LC connectors, –Splitters Fibre fuser purchased, will start tests Mapping –Georges Aad & Michael Begel have been working on mappings since Spring –Work well progressed –Schedule for documentation to be written in September, but not happened yet 15 October 2015Ian Brawn, on behalf of L1Calo8 FOX, block diagram FOX Demonstrator Module

TREX PDR held on 31st July –PDR Agenda: –Specification: 71/ /0.2 –Report now public: – Design approved –TREX not part of TDR design –Approval: panel recommends TREX be adopted by ATLAS Actions identified include –Investigations into MGT clocking scheme Power & cooling Fibre mechanics  Manufacture Q Recruitment required 15 October 2015Ian Brawn, on behalf of L1Calo9 TREX Block Diagram

FTM Simpler design than eFEX but same PCB material & build 2 assembled FTMs delivered –Initial tests underway –Some problems connecting with JTAG chain Firmware development –Control IPBus readout of FPGA temperatures and voltages added Work on MGTs underway 15 October 2015Ian Brawn, on behalf of L1Calo10 FTM Prototype

Link-Speed Tests Hardware Schedule –Slip in eFEX schedule  link-speed tests late January LAr informed –jFEX will arrive too late for LAr deadline L1Calo must define how extrapolate from eFEX test results to jFEX conclusions LAr–L1Calo Meeting 15th Oct, 4pm – –Discussion of Schedule: to fix dates of tests Test Lab: location, identification of joint infrastructure –Long-term facility for LAr-L1Calo-etc. tests Firmware: requirements, link protocol, test patterns Test Plan: Review of latest document Manufacture additional gFEX to provide focus for test rig commissioning? –Evaluate schedule to assess benefit 15 October 2015Ian Brawn, on behalf of L1Calo11
