  1. 设置low freq 128 ,high freq 0 (最大) python3 ocsdiag.py -i 10.57.216.97 -e 8 -s all -c reg-wt -p lowfreq_eq -v 128 python3 ocsdiag.py -i 10.57.216.97 -e 8 -s all -c reg-wt -p highfreq_eq -v 0

  2. 设置tia_peak 为 100,全局的lane 0和lane 3设置为0(最大) python3 ocsdiag.py -i 10.57.216.98 -e 8 -s all -c tia-peak-tune

  3. 校准ibias python3 ocsdiag.py -i 10.57.216.98 -e 8 -s all -c ibias-auto-tune

  4. 校准mgc python3 ocsdiag.py -i 10.57.216.98 -e 8 -c rtmr-prbs python3 ocsdiag.py -i 10.57.216.98 -e 8 -s all -c mgc-auto-tune

  5. 查看retimer 误码情况 python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr all"

  6. 查看眼图情况 python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr 1 eye 1 a" python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr 2 eye 1 a" python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr 3 eye 1 a" python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr 4 eye 1 a"

    如果眼偏下,则op_current需要调小。

先用vgc = 255,校准,然后手动改为200,发现recovery没增加了。
