9 Performance Testing Measured in the lab, need to measure in the Hall next?

Performance Testing What’s next? Activity – Performance Testing Establish trigger distribution connections (Fiber) to all crates Global Crate o Establish CTP  SSP fiber link connections o Initial GTP and TS Trigger functions appear to work well o 2 nd TS crate added for FDC and CDC for independent readout Is this a permanent solution? o Limited high rate testing accomplished with TOF, Global and TS crates Cosmic Ray trigger testing successful FCAL, BCAL, TOF BCAL with FDC and CDC -TAGH crate remains in the Tagger area for another week 10

Activity – Performance Testing  Trigger system hardware design goals need to be tested and verified  The CODA/DAq/Network/EB/ET hardware and software testing ran into issues, so there may not be enough time before 1 st beam to fully test the Trigger system at design goal rates. (200KHz)  High rate (>10KHz?) not required for initial beam commissioning in the next month. 11 Performance Testing What’s next?

Activity – Performance Testing  Firmware features and tools exist to fully test the front end hardware and trigger modules without detector signals. -- Test procedure { Use ALL DAq crates }  Use “Playback” mode to simulate low or high occupancy in FADC250 crates.  Configure readout mode for Integral value. [Reduce data size per trigger]  Configure BUSY assertion level in FADC250 crates  Configure L1 CTP boards for Energy Sum, or Bit-Patterns  Use TS to produce TRIG2 command at random rate. -TRIG2 is used to start the “Playback” waveform -Use TRIG2 to test rate up to 200KHz  VERIFY  Trigger counters – All boards, All crates  Clock counters – All boards, All crates  Sums and Bit-Patterns should be deterministic and align without issue  Test duration - How long will the system remain error free? - At what rate does the system become unstable? 12 Performance Testing What’s next?

Activity – Performance Testing  Would be nice to have expert ‘screens’ for diagnostics of Trigger boards. - Every board has FPGA temperature and voltage registers for readout - May be a good idea to log these at a slow rate (back round process?)  Other diagnostic tools that will prove very useful in the future should use small scale DAq/Trigger setups that include the TS-TD crate, Global Crate and a single L1 crate. - This type of 3 crate tool would use “Playback” data to quickly run deterministic Trigger testing and verify that all timing, FO links, Gigabit Serial transport hardware is functioning properly. 13 Performance Testing What’s next?

Summary All Global Trigger and Trigger Distribution hardware installed All Trigger FO trunk lines are installed and tested Firmware released for all boards is stable - Final testing and verification in progress for CTP applications Essential CODA library development and library release is complete for almost every board. GTP still going through final iterations. High rate performance testing still needs to be completed and documented -Tools for “Playback” mode testing exist 12GeV Trigger hardware meetings have concluded, but meetings for specific trigger application development in each Hall will continue. Questions? 14
