  1. DOMMB Test Plan at LBNL Azriel Goldschmidt IceCube Collaboration Meeting Mons, Oct 2003

  2. Goals of DOMMB Test Plan • Select well functioning DOMMB boards (including delay board) suitable for integration into DOMs to be deployed in IceCube/IceTop. • For boards which are not well functioning, provide information to aid understanding, debugging and fixing. • Provide some DOMMB characterization: optimum running parameters, etc. • Be able to handle an expected “steady state” flow of 55 boards/week with a 2 week latency

  3. First Steps… • Visual Inspection • Power Board • Load “released” firmware and software in dedicated setup (1 board at a time) • Verify reasonable power consumption • Get “boot prompt” and tests that cannot be done in DOR-based setup (if any)

  4. DOMMB Burn-in • Multiple heating and cooling cycles (+65C to -40 C) to catch infant mortality cases. • Boards powered and some testing during burn-in • Power cycles during burn-in • Full operational test at the end to identify bad boards.

  5. Testing Setup • STF (Simple Test Framework) based: STFServer (DOMMB) and STFApp (Test-Control PC) • All tests defined with Pass/Fail and Input and Output Parameters • All Info saved to database (db) • A db query program to see waveforms, output parameters, histograms, etc.

  6. Example of STF test atwd_pulser_spe test Average of 1000 waveforms in 1 sec.
