5.1.6.11. SMTG Hub Time of Day Synchronization

To maintain time synchronization between the HPS and EMACs, a precise relationship between HPS system timer and EMAC’s time of day (ToD) must be established. A similar concept applies for EMACs when exported to the FPGA fabric, a precise relationship between the local ToD (soft IP in FPGA fabric) and EMAC’s ToD must be established as well to maintain time synchronization.
