TDCB Progress

All PCB already produced (100 pcs)

First batch of 10 boards produced and tested with no issues

All the components for the full production arrived this week in CERN.

The company will start the assembly of the remaining 90 boards next week

The test of all the boards will start in few weeks

  • All PCB already produced (93 pcs)
  • First batch of 5 boards produced and tested:
    • 3 with no issues
    • 2 with some problems:
      • TEL62v3-001: problems on JTAG chain and on programming PPs FPGA via EPCS64;
      • TEL62v3-003: a short in one of the ECS lines (under PP0 FPGAor J20 connector)

  • TEL62v3-001 and TEL62v3-003 sent back to the manufacturer for more investigations and repair:
    • X-Ray in 2D and 3D didn’t report any anomalies on the boards
      • Finally the company unsoldered one FPGAon 001 and one FPGAand a connector on 003
      • After unsoldering the short on 003 disappeared

  • New FPGAs were soldered on the boards (yesterday) and both will be sent back to Pisa for testing (next week…)

  • Most of the FPGAs for the production (75 %) will be in CERN on March 18th, the remaining some weeks later
  • The assembly company is ready tostart (they are waiting for the FPGAs)
  • The idea is to splitthe production in 3 batches: 10 + 40 + 38
  • We hope to start the tests of the first batch beginning of April

  • Firmware:
    • One important annoying issue of the TEL62 firmware was the hung of the processing in presence of a big flux of data (noisy channels for example). This was also shown here during the last dry run
    • In Pisa we were able to reproduce the problem (or at least the same symptom) : the system was hunging when exactly 256 words per time-slot were received by the PP
    • After some firmware modifications the problem disappeared, so we hope that was solved

To confirm it, we have to test the system at CERN with a TEL62 attached to a detector with real noise (MUV3 for example)
