Hi,
Customer reported an issue during the mass-production development evaluation phase where `de_regen_lck_raw` remained at 0 during the pre-resolution check.
During the input resolution verification process,
wait 100ms and check `v_locked_raw`;
`v_locked_raw = 1`
perform pre-verification checks (4 retries × 25ms):
`de_regen_lck_raw = 1`
`tmdspll_lck_a_raw = 1`
`stdi_dvalid_ch1 = 1`
However, a phenomenon is occurring where `de_regen_lck_raw` results in 0 during this pre-resolution-verification check (occurrence frequency is less than 1%):
`de_regen_lck_raw = 0`
`tmdspll_lck_a_raw = 1`
`stdi_dvalid_ch1 = 1`
The customer has requested a response as soon as possible.
Please explain the possible causes for `de_regen_lck_raw` becoming 0.
Best regards,
