DUNE DAQ Firmware David Cussans Firmware Meeting 16/Jan/20 You Inst Logo You Inst Logo

Goal • Demonstrate upstream DAQ functions in firmware before design review - Have implementation ready before May 2020 • 10-second buffer • Hit finding • As first step, hit finding in ProtoDUNE - Best source of data - Must complete while Lar in detector • Currently planned – DAQ Mondays until 30/March/20 • See https://indico.fnal.gov/event/22704/contribution/1/material/slides/0.pdf for schedule You Inst Logo 2 Presenter Name | Presentation Title You Inst Logo

Infrastructure ● “33b” Interface. Same for WIB data and hit output – source in hardware (Wibulator++ ) ● Alessandro – sink in hardware ● Erdem – sink/source in simulation ● Written by Simone – Documentation. ● Probably best a README.md in Gitlab, pointed to by Twiki. – Python routines for easy access ● Who?
