Generating the Subsystem for 1588 Operation - 7.2 English

To configure the subsystem with IEEE 1588 hardware timestamping support, open the AXI Ethernet AMD Vivado™ IDE and perform the following steps:

1. From the Physical Interface tab, select the 1000BASE-X or SGMII option.
2. From the Network Timing tab, select the Enable 1588 option.
3. For 1-step and 2-step support, ensure that the 1 Step option is selected; if only 2-step functionality is required, then select the 2 Step option to save on logic resources.
4. Select whether to include logic that supports either the Time-of-Day (ToD) timer and timestamp format, or alternatively to support the Correction Field Format timer and timestamp format.
5. Accurately enter the clock period, in picoseconds, of the 1588 System Timer reference clock period. This is the clock provided to the system timer clock port of Table 1.
6. Click OK to generate the subsystem.
