Board schematics
- File:SCH-DS-xDM-Rev0.PDF
- note: FPGA pin annotations ("IO", "SCLK", "PCLK", etc) on the schematics are bogus, instead, trace them to the FPGA pins.
- note: ENC A is J800, ENC B is J801, ENC C is J900 (schematic name to enclustra name)
- note: Enclustra special pins: "GC" is "clock capable", "HDGC" is "clock capable", "MGTREFCLK" is MGT reference clocks.
- board modifications:
- ethernet mac chip
- NIM output (no U15, etc)
- RJ45 wrong pinout (board mod or special ethernet cable)
- 125 MHz clock mods (TBW)

Clock distribution
Simplified:
- 125 MHz osc -> CLK_XO_125 -> MGTREFCLK0_A -> not used
- 125 MHz osc -> CLK3_XO_125 -> MGTREFCLK1_B -> SFP RX ref clock, QSFP RX and TX ref clock (this is not final design!)
- (disconnected) 125 MHz osc -> CLK2_XO_125 -> FPGA AG8,AH8 (GC)
- 125 MHz osc -> C.C. in1
- C.C. in0 <- CLK_EXT1 (10 MHz GPS clock)
- C.C. in1 <- 125 MHz osc
- (disconnected) C.C. in2 <- CLK_CC_IN <- MGTREFCLK0_D <- SFP RX clock (cannot be used because of uncontrollable phase)
- C.C. in2 <- CLK2_XO_125 <- FPGA AG8,AH8 (GC) <- SFP RX recovered 125 MHz clock
- C.C. in3 <- CLK_FB
- C.C. 125 MHz -> CLK_CC_OUT0 -> MGTREFCLK0_B -> QSFP RX and TX ref clock (final design)
- C.C. 125 MHz -> CLK_CC_OUT1 -> MGTREFCLK1_D -> SFP TX clock
- C.C. 62.5 MHz -> VX clock fanout
proposed changes:
- add C.C. 125 MHz -> new CLK_CC_OUT2 (old CLK2_XO_125) -> FPGA AG8,AH8 (GC)
- change C.C. in2 <- new CLK_CC_IN <- FPGA AK8,AK9 (non-GC)
Complete:
125 MHz oscillator - U5 fan out - q0 -> CLK_XO_125 -> ENC C72,C74 -> FPGA R7,R8 MGTREFCLK0_A (not used) q1 -> U6 C.C. in1 q2 -> CLK3_XO_125 -> ENC C7,C9 -> FPGA J7,J8 MGTREFCLK1_B -> SFP RX reference clock, QSFP RX and TX reference clocks (not final design!) q3 -> disconnected on the board, was CLK2_XO_125 -> ENC C151,C153 -> FPGA AG8,AH8 (GC) U6 C.C (clock cleaner) - in0 <- CLK_EXT1 (presumably GPS 10 MHz ref clock) in1 <- 125 MHz oscillator via U5 in2 <- (was: CLK_CC_IN <- ENC B10,B12 <- FPGA D9,D10 MGTREFCLK0_D <- SFP RX clock, 125 MHz) in2 <- CLK2_XO_125 <- ENC C151,B153 <- FPGA AG8,AH8 (GC) <- mgt_link_data_to_processing.rx_data_clk (SFP RX data clock, 125 MHz) in3 <- CLK_FB out0 -> CLK_CCA -> U12 (125 MHz) out1 -> CLK_CCB -> VX1..6 (62.5 MHz) out2 -> CLK_CCC -> VX7..12 (62.5 MHz) out3 -> CLK_FB into in3 CLK_CCA -> U12 (125 MHz fan out) -> Q0 -> not used Q1 -> CLK_CC_OUT0 -> ENC C3-5 -> FPGA L7,L8 MGTREFCLK0_B -> QSFP RX and TX reference clocks (final design) Q2 -> CLK_CC_OUT1 -> ENC B3-5 -> FPGA B9,B10 MGTREFCLK1_D -> SFP TX clock Q3 -> not used Q4 -> not used Q5 -> SMA J9/J10 CLK_TP0 - FPGA N7,N8 MGTREFCLK1_A - ENC C69,C71 - DS-DM SMA J11, J12 (NOT IN CDM PROJECT) Notes: * CLK_XO_125 (125 MHz osc) is not used * 62.5 MHz VX clock does not go into the FPGA * CLK_EXT0 going to in1 of U5 cannot be used. only permitted frequency is 125 MHz (it drives the MGT reference clocks) and is this frequency is too high for LEMO cables and connectors Proposed modifications: - CLK_CC_IN: from FPGA output pin (ENC C142,C144 - FPGA AK8,AK9) to clock cleaner in2 (instead of CLK2_XO_125 pins) - CLK_CCA -> U12 -> currently unused out3 -> CLK2_XO_125 FPGA pins - repurpose CLK_EXT0 at GPS 1pps/IRIG input to FPGA
I2C bus
- I2C_SCL is J-ENC-A pin 111 I2C_SCL is FPGA I2C_SCL_PL AB13 (IO_L1N_TOL1D_64) and I2C_SCL_PS F18 (PS_MIO10)

- XU8 secure EEPROM ATSHA204A at 0x64, this is 0110'010X -> linux _011'0010 is 0x32. (but responds to scan and read at 0x33)
- U4 ethernet mac chip, EEPROM at 1010 A2 A1 A0 X and MAC/serial_no at 1011 A2 A1 A0 X. A0=VCC, A1=VCC, A2=GND -> linux _101'0011 and _101'1011 is 0x53 and 0x5B.
- U6 clock chip, address 1101 0 A1 A0 X. A1=VCC, A0=N/C (internal pull-up) -> linux _110'1011 is 0x6b
- U23 voltmeter at 10011 ADR1 ADR0. ADR0=GND, ADR1=VCC -> linux _100'1110 is 0x4e
- SFP, address 1010000X -> linux _101'0000 is 0x50. also 0x51?
- QSFP0, QSFP1, QSFP2, QSFP3 (QSFP0_SEL, QSFP1_SEL, QSFP2_SEL, QSFP3_SEL)
I2C clock builder connection
- use Silicon Labs USB "Clock builder pro field programmer", www.silabs.com/CBProgrammer
- connect rainbow jumper cable pins:
- black - 1-GND to GND on DS-DM
- white - 3-SCLK to SCL on the DS-DM
- grey - 7-SDA_SDIO to SDA on the DS-DM
- power up the DS-DM
- plug USB programmer into Windows laptop
- on Windows, run "ClockBuilder Pro"
- it should report "Field programmer detected", press "EVB GUI"
- in EVB GUI, press "Config", set I2C address 0x6B
- press "Scan", it should find Si5394A-A-GM
- select the "Status" tab, should see real-time status of clock chip
GDM MGT configuration
- TX configuration:
- GDM MGT transceivers are configured as "multilane" TX and RX.
- there is 12 TXes ("lanes")
- MGT reference 125 MHz clock goes into [2:0]gtreclk00_in and [11:0]gtrefclk0_in
- one MGT is designated as "master"
- PLL of master MGT converts reference clock into common TX clock and common tx_user_clk2 which becomes tx_data_clk
- common tx_user_clk2 aka tx_data_clk goes into all TXes and clocks tx_data.
- tx_user_clk2 aka tx_data_clk is 125 MHz but not same phase as MGT reference clock.
- RX interim configuration:
- there is 12 RXes ("lanes")
- each RX produces it's own recovered RX clock
- "multilane" configuration assumes all RX recovered clocks run at the same frequency (TX on the other end are driven by common TX clock, see above), but have different phase
- one RX recovered clock is designated as "master" (rx_user_clk2 aka rx_data_clk) and a phase-matching fifo/buffer is used to bring rx_data from all 12 RXes to this common rx_data_clk
- this works because each CDM SFP TX runs on the SFP RX recovered clock which is frequency-locked with the GDM QSFP TX clock.
- RX final configuration:
- MGTs permit using the common TX clock (tx_user_clk2 aka tx_data_clk) as the common rx_data_clk (they are frequency locked through the CDM).
- this permits use of tx_data_clk as the main clock domain in the GDM and removes the need to bring rx_data into the tx_data_clk domain (actually this is done in the MGT RX phase matching fifo/buffer).
Clock path
- interim configuration:
- GDM MGT reference clock 125 MHz
- -> tx_data_clk 125 MHz -> TX clock 2.5 GHz -> GDM QSFP TX
- -> CDM SFP RX -> RX recovered clock 125 MHz -> CC_CLK_IN
- -> CDM C.C. -> CC_CLK_OUT1 -> CDM SFP TX data clock 125 MHz -> TX clock 2.5 GHz -> CDM SFP TX
- -> GDM QSFP RX -> 12x recovered clocks -> one of them is "master" recovered clock rx_data_clk
- final configuration:
- -> GDM QSFP RX -> 12x recovered clocks -> 12x phase matching fifo/buffer -> tx_data_clk
Clock domains
GPS
- no GPS : GDM runs from internal 125 MHz oscillator
- external 10 MHz clock : GDM runs from external 10 MHz clock and optional 1pps signal (use VME-NIMIO32 NIM outputs)
- GPS receiver : GDM runs from GPS 10 MHz clock and GPS IRIG serial data
- LNGS GPS:
- provides 1pps and serial data over fiber from GPS receiver (master). LNGS xxx box is not used.
- serial data goes to GDM, decoded, 1pps signal extracted, goes to LEMO output
- 1pps from GDM is used to train the Rubidium clock which provides a 10 MHz clock
- 10 MHz output from Rubidium clock goes to GDM 10 MHz external clock input

Board test plan
To test:
- Enclustra FPGA board
- SFP port - RX data (ok), TX data (untested), LOS (untested), i2c (ok), SFP_RS0 connected to QSFP0_SEL is wrong? our Finisar SFP says RS0, RS1 N/C, so probably okey.
- GDM QSFP ports (lanes 0,1,2. lane 3 n/c). RX data, TX data, i2c
- SW5 CLK_EXT1 NIM works. TTL needs to be tested. flipping SW5 CLK_EXT0 side from NIM to TTL makes CLK_EXT1 go LOS and OOF in the clock chip. R23 and R53 should be removed?
- BOOT_MODE 0 and 1
- I2C bus. tested all devices except for QSFP.
Partial:
- U23 3.3V current meter and thermometer. V1,V2 is current monitor, same as in application note. V3,V4 is thermometer, same in application note, except capacitor C118 is 0.1u instead of 470pF. Tested ok: Tint, VCC, V1, V2, V1-V2. Test failed: TR2 reads 50-something degC instead of same as Tint.
Done:
- LED_FP1A..D: tested ok. K.O. 15 sep 2022
- USB UART: tested ok. K.O. 15 sep 2022
- J4A, J4B, J5A, J5B LEMO inputs (NIM/TTL) EXT_IN_LV(1..4). TTL threshold 1.7V, NIM threshold -0.3V. 50 Ohm termination. TTL straight, NIM inverted.
- J6A, J6B LEMO clock inputs: 10 MHz TTL from chronobox works, 10 MHz NIM from IO32 works. 18-apr-2023
- J7A, J7B LEMO outputs EXT_OUT(1), EXT_OUT(2) (NIM/TTL) (tested 23nov2022, K.O.). TTL ???, NIM inverted.
- TTL out no 50 ohm termination: 0=0V, 1=5V, rise and fall time ~5 ns
- TTL out with 50 ohm termination: 0=0V, 1=2.5V, rise and fall time <2ns
- NIM out no 50 ohm termination: 0=+50mV, 1=-1.8V, rise and fall time ~3ns
- NIM out with 50 ohm termination: 0=0V, 1=-0.9V, rise and fall time <2ns
- ethernet MAC i2c chip (K.O. 20sep2022: can read: i2cdump 0 0x5b, nov2022 have u-boot driver)
- CDM VX ports 2x(CLK, 3 tx, 4 rx) tested using test_cdm.exe and LVDS loopback in VX firmware.
Failure:
- ethernet: does not connect to alliedtelesys switch. connects to my USB-eth adapter at 100 Mbit speed. uboot mii status reports connection speed oscillating between 1000, 100 and 10. K.O. 16-sep-2022

also this should have worked if i2c_xxx() functions were enabled in uboot:

- https://github.com/Xilinx/u-boot-xlnx/blob/master/board/xilinx/common/board.c (zynq_board_read_rom_ethaddr())
Note:
- 0x5B is the i2c chip address
- 0x9A is the data offset inside the chip, see datasheet or i2c read dump above.

copy to SD card:
open a root shell format 16 GB Sd card per above cd /home/dsdmdev/git/ds-dm-gcdm make copy (cannot confirm it worked, DS-DM CDM sn 6 serial console is broken)
prepare bootable sd card
format the sd card
this only needs to be done once
- become root
- cd ~olchansk/git/ds-dm-gcdm
- use "lsblk" to identify the SD card (should show as 8/16/32 GB block device)/ /dev/sdd in this case
- make sdcard_format SDCARD_DEVICE=/dev/sdd
- disconnect sd card, reconnect the sd card (to detect new partition tables, etc)
copy CDM boot files
cd /home/dsdmdev/git/ds-dm-gcdm make copy
copy boot files to the sd card
- as root: identify partition labels, run "blkid", should say "BOOT", "rootfs" and "data"
- mount
mkdir /media/olchansk/BOOT mkdir /media/olchansk/rootfs mkdir /media/olchansk/data mount -L BOOT /media/olchansk/BOOT mount -L rootfs /media/olchansk/rootfs mount -L data /media/olchansk/data cp PetaLinux_GDM_CDM/images/linux/BOOT.BIN /media/olchansk/BOOT/ cp PetaLinux_GDM_CDM/images/linux/boot.scr /media/olchansk/BOOT/ cp PetaLinux_GDM_CDM/images/linux/image.ub /media/olchansk/BOOT/ umount /media/olchansk/BOOT umount /media/olchansk/rootfs umount /media/olchansk/data eject /dev/sdd

VX setup
- general
- Start acq from user code = y, all others = n (as of Mar 2023: will start when first trigger received)
- Use NIM IO = y
- Use external clock = y
- LVDS quartet is input = n, y, n, y
- LVDS quartet mode = User, User, User, User
- trigger from front panel NIM:
- Trigger on external signal = y, all others = n
- connect CDM EXT_OUT(2) to VX "TrigIn"
- trigger from LVDS "Sync" mode
- Trigger on LVDS Sync signal = y, all others = n
- LVDS quartet mode = User, Sync, User, User
- trigger from LVDS "User" mode
- Trigger on LVDS pair 12 signal = y, all others = n
- LVDS quartet is input = n, y, n, y
- LVDS quartet mode = User, User, User, User
GDM setup
- GDM is gdm0
- set inputs to NIM mode
- set outputs to TTL mode (this GDM has wrong NIM output circuit)
- use top QSFP slot, connect split cable 1 into CDM01, cable 2 into CDM02
- connect non-inverted NIM trigger signal to top-LEMO-left EXT_IN_LV(1)
- connect non-inverted NIM TSM signal to top-LEME-right EXT_IN_LV(2)
- GDM LEDs: TRIG, TSM, trigger enabled, trigger_out
- GDM LEMO_OUT: trigger, trigger
CDM setup

DS-20K DAQ
Overview
DS-DM, GDM and CDM are key parts of the DS-20K DAQ system:
- common clock distribution from external clock (atomic clock, GPS) to GDM to per-quadrant CDMs to VX digitizers
- common trigger distribution from GDM internal algorithm or external input to all VX digitizers
- run control: GDM, CDM, VX all start recording data at the same time (clock and timestamp reset)
- collection of trigger data from VX digitizers to per-quadrant CDMs to GDM
Deliverables
- hardware and firmware for GDM to CDM clock distribution
- hardware and firmware for CDM to VX clock distribution
- hardware and firmware for GDM external clock input (atomic clock or GPS)
- hardware and firmware for CDM and VX serial communications (VX LVDS I/O connector)
- firmware for run control (timestamp reset and sync): GDM to CDM to VX
- firmware for common trigger distribution: GDM to CDM to VX
- firmware for trigger data flow: VX to CDM to GDM
- firmware for busy control: VX to CDM to GDM back to CDM to VX
- firmware for flow control: FEP to GDM MIDAS frontend to GDM to CDM to VX
- GDM MIDAS frontend: clock selector and monitoring, trigger and run control, busy and flow control, GDM housekeeping
- CDM MIDAS frontend: clock monitoring, CDM housekeeping

Technical risk items
this refers to unexpected behaviour and performance of system components, causes big difficulty in implementing the system, prevents delivery of deliverables, and prevents or negatively affects operation of the DS-20K DAQ or of the whole experiment.
(14-sep-2022, list is not sorted by any criterial: severity, probability, ease of investigation)
(stability of course is long term stability, across hours, days, weeks, months, years)
- stability of Enclustra FPGA modules (crashes/year, failures to boot/year, flash corruption/year)
- stability of GDM external clock PLL (lock loss/year)
- stability of CDM recovered clock (lock loss/year, unexpected phase drifts, etc)
- unexpected failures or bit error rates in GDM-CDM fiber links
- stability of CDM VX clock outputs (stability of clock cleaner chip)
- stability of VX internal clock distribution (VX PLL lock loss events)
- stability of VX CAEN base firmware (different versions of CAEN base firmware have different clock distribution behaviour)
- strange things in CAEN base firmware (unexpected clocking of LVDS I/O, unexpected phase shifts between clocks, etc)
- DS-DM and VX hardware problems (incompatible LVSD I/O, incompatible clock signals, etc)
Milestones
(14-sep-2022: at this stage of the project, priority must be given to identifying and retiring (so called) technical risk factors. it is not good to build the complete system only to discover that (for example) some Enclustra FPGA modules require 5 attempts to boot and erase their flash memory contents once a month. Both example are real-life actual problems that caused big difficulties in GRIFFIN/TIGRESS and ALPHA-g experiments).
Development and testing milestones in time reversed order:
- full DAQ data challenge: all VXes, CDM, GDM, network, FEP, TSP, MIDAS operate as designed
- one quadrant data challenge: 1 VME crate of VX, CDM, GDM, network, FEP, TSP, MIDAS operate as designed
- vertical slice data challenge: 1 VME crate, 2 VX, 2 CDM (1 VX per CDM), GDM, etc operate as designed
- GDM-CDM link finalized (data rate frozen, data packet format frozen, data content permitted to change)
- CDM-VX serial link finalized (data rate frozen, data packet format frozen, data content permitted to change)
- run control (timestamp reset) and trigger distribution design agreed upon, frozen (list of possible triggers permitted to change)
- VX to CDM to GDM data flow design agreed upon, frozen (data contents permitted to change)
- major technical risk items retired (all hardware and firmware is working as expecred without mysteries and surprises, all problems are identified, investigated, resolved, solutions tested)
- stable operation of CDM-VX serial links in vertical slice system
- stable operation of GDM to CDM clock in vertical slice system
- stable operation of CDM to VX clock in vertical slice system
- vertical slice system assembled (1 VME crate, 2 VX, 2 CDM, 1 GDM, network, FEP, TSP, MIDAS)
