| Register | Value | Comments |
|---|---|---|
| dllEnable | True | Enable DLL clock for for retiming |
| dllCapReset | False | |
| dllForceDown | False | DLL can have harmonic lock problem which would need dllForceDown=T to release it |
| dllChargePumpCurrent | 0x0 | Set charge injection current to min value. Higher current enables faster locking but may cause larger jitter. We care less about locking time but care more about jitter. |
| dllClockDelay | scan | Scan this delay for the active channel for good BER window bathtub. |
Vakhtang's readout software
Vakhtang Tsiskaridze (VT) wrote a standalone python package to perform digital scans outside of YARR. Use the following steps to run on felix.
For all windows (4 in total are needed):
| Code Block |
|---|
# Login and setup
ssh daq@felix # password: slacrce
cd ~/daq
source complete-setup.sh
cd ~/daq/itkdaq |
Window #1:
| Code Block |
|---|
# Monitoring for Tx sent to FELIX
./run-felix-toflx.sh |
Window #2:
| Code Block |
|---|
# Monitoring for Rx returned from FELIX
./run-felix-tohost.sh |
Window #3:
| Code Block |
|---|
# Runs an instance of felix-star
python run_readout.py |
Window #4:
| Code Block |
|---|
# Starts interactive session where configuration and digital scans are steered
python -i run_sendcmd.py>>> repower_init() # Quick power cycles the module and initializes with nominal configurations
>>> full_scan() # Must be done 2+ times, see (1) below for example of output |
| Code Block |
|---|
# Output after first full_scan()
