Occasional ContributorCalculate skew timing with Cyclone V and ksz9031
hello,
i have troubles with the ethernet bandwith and retransmissions (ack). after some diagnostic i think it is an timing issue.
the wire length from the fpga -> knz9031 is:
mil

Regular ContributorHello,
Can you provide some updates?
I cannot get any confirmation with internal team on the best skew calculation.
But the normal practice is to start with measuring a working window, get the min and max skews then use the midpoint and fine tune it as you wish. I think you have done this already.
If it is working on the hardware then it should be fine.

Occasional Contributorhello,
but how about the wire length?
sould be the resistor considered?
how would be the "best" timing for our board?
thanks
