Why is there a mismatch in the PFC width between the theory calculation and the hardware measurement in the GTS Ethernet Hard IP design? - Why is there a mismatch in the PFC width between the theory calculation and the hardware measurement in the GTS Ethernet Hard IP design?
Description You might observe a mismatch in the PFC width between the theory calculation and hardware measurement at max PFC quanta. This is due to the alignment marker (AM) pulse window within the PCS data, which is causing this variation. Resolution Estimating the deviation of the PFC width from the expected value is not feasible. Quanta variation is not quantifiable, and the variation is expected. There is no plan to fix this problem.
