3. CLB in DOMs for PPM-DU Organisation tests of Valencia-CPB (Diego) Firmware / Data format for PPM-DU (Maarten) Order of test crate (for 1 DOM) to be made by Saclay: – Already interest from Valencia (Diego) APC (Antoine) Nikhef (Ruud) Genova (Marco D’A) ECAP? (Uli) – Inventory to be made complete (Tassos) – Price to be provided (Frederic)

4. CLB functionality Defined by Saclay’s CLB prototype Documentation at wiki: Frederic

5. In the following slides Results of the discussion on the CLB-meeting of 5 September in APC In yellow boxes the work to be done In the white boxes: names of institutes/persons working on the work specified in the yellow boxes In the with boxes: the targeted delivery date Please, note that this is a tentative list of names (which is to be verified) Please, add institutes/names where applicable

6. FPGA requirements Operating system (processor?) Power consumption Costs Clock extraction TDC channels TDC resolution/serial link speed Dynamic reconfiguration  Documented FPGA choice Names: IFIC, Diego Real Nikhef, Peter Jansweijer APC, Cédric Champion When: 1 October 2012

7. Check of FPGA choice Buy evaluation board Check TDC implementation Check synchronisation  Verified FPGA (Note: CLB board layout starts already earlier) Names: IFIC, David Calvo Nikhef, Peter Jansweijer APC, Cédric Champion When: 1 December 2012

8. CLB design upgrade Define test interface on-board Justify decision on integration instrumentation vs use of piggy- backs On-shore: mirror of CLB – Instrumentation Setup communication layer+ configuration Explore multiple I2C lines Are all sensors always active: control?  Proto-design CLB Names: IFIC, David Calvo Nikhef, Peter Jansweijer When: 1 December 2012

9. Data format Define precisely data frame size and data format (impact on DAQ architecture and network) Define timing requirements setting Take into account scalability  Documented data format Names: INFN-Bologna, Simone (?) Nikhef, Maarten When: 1 December 2012

10. For DOM production Development of test setups for CLB production (Cedric, Christian) Set up of data base for test results Quality management (Christian) Names: APC, Christian Olivettei APC, Cédric Champion When: ….

11. Seafloor network + DU-foot Detailed inventory of requirements for instrumentation in seafloor network – Calibration units? – Data formats? – CLB in DU-foot? – CLB in each JB? Names: CPPM, Patrick INFN, Riccardo Nikhef, Eric When: 1 October 2012

12. Organisation Put all information directly on the WPF/L wiki Minutes of all (smaller) meetings on the WPF/L wiki (http://wiki.km3net.physik.uni- erlangen.de/index.php/Electronic_group#WPF.2FL_Meetings)http://wiki.km3net.physik.uni- erlangen.de/index.php/Electronic_group#WPF.2FL_Meetings (alternatively, km3net.org  internal  WPF/L wiki  electronic group) (km3net, pyrosoma) The current mailing list can be found at the Indico pages (participants if you enter as manager); must be setup in KM3NeT portal (Els) Video/telcons full group – Bi-weekly first, later more relaxed – Next video-con: 19 September 2012, 10-12h – http://agenda.nikhef.nl/conferenceDisplay.py?confId=2080 http://agenda.nikhef.nl/conferenceDisplay.py?confId=2080 – Please add anything you want to share/discuss during the meeting to your name

13. FPGA considerations Pushing data! Revisit timing scheme (White Rabbit) Use tiny-TCP for data to DOM Use UDP from data Open cores in FPGA
