SPD - DAQ Hw Integration Common data headers (CDH) produced by routers using trigger information (bunch crossing, orbit number, L2 messages, etc…) CDH checking enabled in DATE and tested with low trigger rate (SEB, misalignment between L2 message and BCNT in MEB mode) SPD Status bits (Block attribute) used to define synchronization and missing triggers between HSs. SOD / EOD information integrated in common data header and tested with ECS Extra data header produced during calibration runs Basic data format checking embedded in the routers System tested extensively in DSF with 10 routers (20 in the experiment) and used to develop performance studies on SPD sectors 11/12/2006 Ivan Amos Calì - 2nd ALICE Integration & Commissioning workshop
