14 ALCT-672 have been shipped to FNAL for on-chamber testing and then shipment to PNPI.
Expect first batch of 22 ALCT-288 in 2 weeks. After approval of assembly job all will be assembled.

10. Problems found (FAST) 11 problem boards Previously seen problems:
ALCT was sending wrong standby patterns.
ALCT loaded with wrong FPGA firmware.
ALCT was noisy. One of the test pulse outputs was always enabled.
ALCT displayed wrong temperature and current. Problem with ADCs.
Connectors improperly soldered.
New problems:
Strange response of any AFEB if plug in
connector #8. (can’t reproduce)
Bad test pulse to all AFEBs.
Couldn’t load 4 boards using svf files.
(can’t reproduce).

11. Trigger Motherboard (TMB)
Input
connectors
From ALCT
Main FPGA
(on back)
XILINX XCV1000E
Mezzanine board
From 5 CFEB’s
Generates Cathode LCT trigger with input from CFEB (comparator)
Matches ALCT and CLCT; sends trigger primitive info via MPC to Lev-1 muon trigger, sends anode and cathode hits to DMB.

12. TMB Integration at UCLA FAST Site
Full set of peripheral crate electronics:
TMB with DMB, CCB
DDU readout through Gbit Ethernet to Linux PC
Also full set of AFEB, CFEB, ME2/2 chamber
Debug whole DAQ readout
Time in DAQ system
Debug trigger modes
Debug new functionalities
Debug new DDU prototype

13. TMB Prototype Status 18 boards assembled and working.
Full set of bench tests.
Testing board built to check inputs and outputs (VME backplane).
Received 3 bad TMBs back from UFL. Tests in progress.
Next set of tests at UCLA with OSU this and next week. Goals:
Integration of the whole system
Full set of trigger patterns
DDU readout (TTCrx)
Separate ALCT and TMB data streams to DMB
High-rate tests
Multi chamber and multi crate readout

14. TMB Future Plans (Hardware)
Real peripheral crates will require a transition module in back to receive signals from ALCT and RPC cables.
Virtex-II mezzanine card were produced to replace Virtex-E.
Produced small PC board for Data Delay Devices chip to replace PHOS4.
Increase TMB-to-DMB data path from 15 to 30 bits wide. Agreement with OSU on backplane pins and signal assignments.

15. PHOS4 Replacement New Delay chips
TMB uses PHOS4 chips for adjusting 10 clock delays (CFEBs, ALCT, DMB and RPC).
Trying out Data Delay Devices (3D3444).
Each has 4 channels  PHOS4 5 channels => 3 chips necessary to replace 2 PHOS4 chips.
They have (16x2.0ns) and (16x1.5ns).
First test (2.0ns) duty cycle 68/32 for data sent from CFEB to TMB
New Delay chips

16. TMB Firmware Changes Future improvements: Changes made :
Added DiStrip and multiple patterns.
DMB pre-trigger can pre-trigger on ½-Strip or DiStrip.
Independent thresholds for ½-Strip and DiStrips.
Replace PHOS4 chips. New firmware necessary. Already done.
Changes in progress (debugging) :
Add DAQ multi-buffer handling capability.
Future improvements:
Add RPC coincidence logic. Useful to solve ambiguities.
Virtex-II FPGA faster by 50% for same cost
(XC2V3000 or XC2V4000)

17. TMB firmware changes Trigger Sequencer:
Now includes Gilmores random active-feb-vector mode
Can require ALCT coincidence to pre-trigger (may not be possible to time-in)
Control signals to Buffer Manager for writing raw hits.
Stores CLCT data in distributed RAM (no LUTs anymore)
Not yet timed in with CFEB module and TMB module.

18. TMB firmware changes (OSU)
CLCT raw hits multi-buffering, 8 events
CFEB section done
New Buffer manager code works for writing
Write timing not yet tuned
Readout section incomplete
Special mode to send random active_feb_flag bits to DMB (when triggered).

19. TMB firmware changes
Added special mode where CLCT pre-trigger always results in L1A request.
Local Dump reads out only hit CFEBs
Add CRC to TMB data stream.
CRC calculator done
Not yet integrated with readout data

20. TMB Logic for tests Proposal for tests this week:
Modify 1 TMB circuit board to work with new DMB backplane signals
Use TMB logic from FAST site version and change ALCT backplane signals
Allows to test TMB with modified DMB
High rate test possible

27. CSC Display Status Added best muon track from TMB
Compiled version available. Runs 10x faster.
Compiled version now available from CMS CVS repository.
Modified display window to display similar information to current FAST site software
Update to read DDU output
Add multiple chamber capability
How to display (several windows?)

28. TMB Readout and Simulation of Throughput
Hardware:
ALCT data now goes directly to a separate DMB FIFO (change)
ME1/1 Worst Case
Simulation result for CLCT readout:
10% of LCTs read out (versus 3% expected)
8 buffers

29. Conclusions ALCT production in excellent shape.
Production of ALCT-672,-288 ongoing.
Testing working fine. Some problems can’t be prevented.
TMB firmware in progress. Many changes implemented.
New tests on the way next week with OSU toward full integration of the system.
