2.1.9. IEEE 1588 Precision Time Protocol for Ethernet

F-tile supports the IEEE 1588 precision time protocol feature for Ethernet hard IP. This feature can only be used by 400G hard IP with MAC enabled. Enabling the PTP feature places a limit on how many hard IPs can be implemented using 200G hard IP because the PTP feature uses EMIB_6 and EMIB_7.

Refer to Topologies for more details. Refer to F-Tile Ethernet Intel® FPGA Hard IP User Guide for Ethernet modes supported with IEEE 1588 precision time protocol.
