Arria 10 Transceiver PHY latency estimation

Hi,

I want to calculate/estimate the latency incurred in transmitting data from the Arria 10 Transceiver PHY IP. I looked into the user guide; it doesn' have any discussion on latency of the blocks, or latency occurred from data received from the FPGA fabric to serial data transmitted from the PMA buffer. My application requires a deterministic latency for the Transceiver PHY and the only thing I could find in the user guide is "the Register Mode [in Standard PCS options] bypasses the FIFO functionality to eliminate the FIFO latency uncertainty for applications with stringent latency requirements."

Please let me know how could I estimate the latency of the Transceiver PHY in transmitting data.

Thanks,
Arvind
