DAQ

• ODB /eq/cb02/settings:
• dl_ctrl for A+B 0xC0FE
• dl_ctrl for A*B 0xC0F0
• A is grand-OR of all scintillators on the TDC-A cable (enabled by dl_trg_mask[7..0], 8 bits for the 8 scintillators)
• B is grand-OR of all scintillators on the TDC-B cable (enabled by dl_trg_mask[15..8], 8 bits for the 8 scintillators)
• each scintillator signal (A[7..0] and B[7..0]) is L*R hardwired in dl/dl.sv
• dl_tdc_mask can be used to disable each of the 32 TDC inputs (see map between TDC inputs and scintillator channels)
• there is no button to disable chronobox counters and rates for individual CB channels

TDC cabling map

This TDC map is hardcoded in the analyzer and in the FPGA trigger logic.

Orange and Black detectors TDC cable connections are the same.

TDC cable A is tdc00..tdc15
TDC cable B is tdc16..tdc31
A signal is tdc32
B signal is tdc33
T = A*B  is tdc34

TDC end  | SiPM | scintillator | SiPM | TDC end
------------------------------------------------
tdc01    |  B1  |  sc01, sc02  |  B2  | tdc14-15
tdc10-11 |  B3  |  sc03, sc04  |  B4  | tdc67
tdc23    |  B5  |  sc05, sc06  |  B6  | tdc12-13
tdc89    |  B7  |  sc07, sc08  |  B8  | tdc45

PPG32-Rev2 settings

Jumper settings

• JMP1 - left (INP)
• JMP2 - left (INP)
• JMP3 - left (TTL input)
• P0 - both right (NIM output)
• P1 - both left (TTL output)
• SW1 - 0 (VME address)
• SW2 - 0 (VME address)
• SW3 - C (VME A24 address 0xC0'0000)

Firmware sources

• cd $HOME/git
• git clone https://bitbucket.org/ttriumfdaq/vme-nimio32 vme-nimio32-dl-clock
• cd vme-nimio32-dl-clock
• git checkout dl-clock

Build firmware

• ssh trinatdaq ### must be Ubuntu-20 to run quartus 13.1
• cd /home/olchansk/git/vme-nimio32-dl-clock/VME-NIMIO32/PPG32-Rev1
• /daq/quartus/13.1.4.182/quartus/bin/quartus
• open VME-PPG32 project, processing -> start compilation
• will produce new sof and pof files (jic file must be regenerated manually)
• load sof file into FPGA using quartus jtag programmer, then load pof file into EPCS16 flasg using srunner, see below

Load firmware

• cd ~olchansk/git/vme
• ./srunner_vme_gef.exe -id -16 /dev/null 0x300020 ### identify EPCS chip
• ./srunner_vme_gef.exe -program -16 /home/olchansk/git/vme-nimio32-dl-clock/VME-NIMIO32/PPG32-Rev1/VME-PPG32.pof 0x300020
• ./test_VMENIMIO32_gef.exe --addr 0x300000 --reboot

Check clock status

• ./test_VMENIMIO32_gef.exe --addr 0x300000 --read 9 ### read clock status, bits are as above
• ./test_VMENIMIO32_gef.exe --addr 0x300000 --write 9 0 ### reset the pll_unlocked_latch
