MTF 7 production status Receved from assembly last week: Ø 1 Base board without Virtex-7 (for power voltages check) Ø 3 Base boards with Virtex-7 Test status: Ø board without Virtex-7 is fine, all power voltages OK, all Control FPGA functionality OK Ø two boards with Virtex-7 are completely fine. All connections tested OK Ø one board with Virtex-7 has assembly problems: v 3 signals are not working: q One in control bus q One in PT LUT interface q One line in DAQ TX pair v Confirmed that all 3 signals are not driven by Virtex-7 v Either defective assembly or broken traces in PCB q Broken traces unlikely because the PCB was production-tested v Requires rework and extra tests v Will not hold full assembly schedule 2015 -03 -30 A.
