Hardware Activies

Giles Barr, David Cussans , Alan Watson 27th April 2018

Outline

• Describe Carrier board for Oxford/SLAC DPM
• Focussed on providing platform to test ideas in

R&D packages.

• ATCA based
• PCIe based

DPM Hardware

• Institutes: Oxford (+SLAC) (+ ?)
• 2 week deliverable: Schedule and task-list for testing.
• 6 month deliverable: DPM boards
• Sub-tasks
• Complete DPM PCB development
• Deliver tested modules
• Develop firmware for RAM and NVM management
• See talk by Matt Graham:

DPM Carrier

• Institutes: Birmingham, Bristol, Oxford, UCL, RAL, Imperial(?)
• Input from SLAC
• Effort: Schematic Capture/PCB layout 0.5 + 0.2 + 0.2 FTE. Signal

integrity 0.1 FTE , Firmware 0.5 + 0.5 + 0.5

• 2 week deliverable: Investigate feasibility of team working and schedule.

Specify hardware and tasks for vertical slice test.

• 3 month deliverable: Schematics and design review, initial PCB layout.
• 6 month deliverable: DPM Carrier, infrastructure firmware.
• 12 month deliverable: Demonstration of protoDUNE readout with DPM

carrier(vertical slice-test of front-end hardware).

• Sub-tasks
• Infrastructure firmware, software
• Separate daughter-board for optics to WIB

DPM Carrier Aims

• Be able to test three scenarios:
• WIB → DPM → Carrier FPGA → CPU (PCIe)
• WIB → Carrier FPGA → CPU(PCIe)
• WIB → Carrier FPGA → DPM → Carrier FPGA → CPU
• Basic functionality of DPM will be tested with COB and perhaps a variant of

SLAC Jig Board

• Act as platform for vertical slice test
• Assume 1.28GBit/s 8b/10b encoded data from WIB

WIB → DPM → Carrier FPGA → CPU

• Topologically

identical to connecting DPM in ATCA to Felix via 10GBit/s links

WIB → Carrier FPGA → CPU(PCIe) / WIB → Carrier FPGA → DPM → Motherboard FPGA → CPU

SP TPC CE Test Platform

• Provide light-weight

test system for CE prototype WIB

DPM Carrier Starting Point

• Aim to use an existing PCIe format card
• + firmware + test software
• Options:
• Felix ( BNL FLX 711/712 board )

■ Firmware is semi-open ( sign up to collaboration, agree not to “Fork” or share with non collaboration members ) ■ Discussing with BNL if access is available to hardware design and collaboration.

• CMS PCIe platform

■ Less mature than Felix

• Open Hardware system

■ E.g. NetFPGA-Sume

• Hardware similar to Felix
• Firmware + Hardware semi-open

Plans

• Select starting point for PCIe platform ( Felix / CMS/ NetFPGA /

Other? )

• Political/financial as well as technical constraints.
• In parallel put in place systems for design interchange, version

management, etc.

• Should be done at collaboration level ( c.f. CERN EDMS )

but only DUNE design management system seems to be for engineering data.

• Learn (move on from) protoDUNE.

■ All new firmware / software in collaboration wide repository.

• Commence hardware + firmware + software design in parallel
