有关intel cpri ip核的delay计算

Hi,

The round trip delay is the sum of the Tx path delays through the REC master and the RE slave, the Rx path delays through the REC master and the RE slave, the cable delay, and the Tx-to-Rx switching delay, sometimes referred to as the loopback delay. The Tx-to-Rx switching delay is labeled T_S_Rx_Tx in the figure. The Tx-to-Rx switching delay depends on the loopback path and the device.

For the further information about the round trip delay, you may refer to link below Section 3.18.3.3, pg 115, https://www.intel.com/content/www/us/en/docs/programmable/683595/23-1-19-7-0/round-trip-delay.html

For the further information about the round trip delay register, you may download the register map file in Section 5,
