2.6.2. Test Procedure—Design Example with the IEEE 1588v2 Feature
Follow these steps to test the design examples in hardware using PMA serial loopback:
Note: The design example starts with default data rate of 25G.
- Perform data rate switching to 10G:
- In Quartus® Prime Pro Edition software, go to Tools > In-System Sources & Probes Editor tool to open the default source and probe GUI.
- Set the source bit[1] in source and probe to 1.
- In the System Console panel, type the following commands as below to set the correct clock period for the required TX and RX MAC clock frequency in 10G speed mode:
reg_write 0xA05 0x66666 reg_write 0xB05 0x66666
- Perform data rate switching to 25G:
- In Quartus® Prime Pro Edition software, go to Tools > In-System Sources & Probes Editor tool to open the default source and probe GUI.
- Set the source bit[1] in source and probe to 0.
- In the System Console panel, type the following commands as below to set the correct clock period for the required TX and RX MAC clock frequency in 25G speed mode:
reg_write 0xA05 0x28F5C reg_write 0xB05 0x28F5C
Note: 0xA05 is register that configure TX_PTP_CLK_PERIOD. 0xB05 is register that configure RX_PTP_CLK_PERIOD. - Perform system reset release after executing the data rate reconfiguration:
- Click Tools > In-System Sources & Probes Editor tool for the default Source and Probe GUI.
- Toggle the system reset signal (Source[0]) from 0 to 1 to apply the reset and return the system reset signal back to 0 to release the system from the reset state.
- Monitor the Probe signals and ensure that the status is valid.
- To perform internal serial loopback test, refer to the Test Procedure—Design Example Without the IEEE 1588v2 Feature section of this chapter.
