Hi,

I believe you can measure the lock time directly by using a counter in fpga

that start counting up after a general reset that is applied to the Rx as well as the counter. The counter to stop when lock is flagged by the serdes Rx.

You can see the final counter result directly in a signal tap(ELA/chipscope) then convert it to time.

Remember there are two stages(A PLL lock followed Rx recovery lock which is what need to measure). Use any suitably fast clock for the signal tap counter
