1.7. Testing the eCPRI Intel FPGA IP Design Example
After you compile the eCPRI Intel® FPGA IP core design example and configure it on your Intel® FPGA device, you can use the System Console to program the IP core and its embedded Native PHY IP core registers.
To turn on the System Console and test the hardware design example, follow these steps:
- After the hardware design example is configured on the Intel® device, in the Quartus® Prime Pro Edition software, on the Tools menu, click System Debugging Tools > System Console.
- In the Tcl Console pane, change directory to <design_example_dir>/synthesis/quartus/hardware_test and type the following command to open a connection to the JTAG master and start the test:
- source ecpri_agilex.tcl for Intel® Agilex™ 7 designs
- source ecpri_s10.tcl for Stratix® 10 designs
- source ecpri_a10.tcl for Arria® 10 designs
- For your Stratix® 10 or Intel® Agilex™ 7 E-tile device variations, you must perform either an internal or external loopback command once after you program the .sof file:
- Modify TEST_MODE variable in the flow.c file to select the loopback mode:
You must recompile and regenerate the Nios® V software whenever you change the flow.c file.
TEST_MODE Action 0 Serial loopback enable for simulation only 1 Serial loopback enable for hardware only 2 Serial loopback and calibration 3 Calibration only - Regenerate the .elf file and program to the board one more time and reprogram the .sof file.
- Modify TEST_MODE variable in the flow.c file to select the loopback mode:
- Test the design operation through the commands supported in the system console script. The system console script provides useful commands for reading statistics and features enabling in the design.
Table 4. System Console Script Commands Command Description loop_on Enables TX to RX internal serial loopback. Use for Stratix® 10 H-tile and Arria® 10 devices only. loop_off Disables TX to RX internal serial loopback. Use for Stratix® 10 H-tile and Arria® 10 devices only. link_init_int_lpbk Enables TX to RX internal serial loopback within the transceiver and performs the transceiver calibration flow. Applicable to the Stratix® 10 E-tile and Intel® Agilex™ 7 E-tile designs only. link_init_ext_lpbk Enables TX to RX external loopback and performs the transceiver calibration flow. Applicable to the Stratix® 10 E-tile and Intel® Agilex™ 7 E-tile designs only. traffic_gen_disable Disables the traffic generator and checker. chkmac_stats Displays the statistics for the Ethernet MAC. read_test_statistics Display the error statistics for traffic generator and checkers. ext_continuous_mode_en Resets the entire design system, and enables the traffic generator to generate continuous traffic packets. dr_25g_to_10g_etile Switches the data rate of the Ethernet MAC from 25G to 10G. Use for the Stratix® 10 E-tile and Intel® Agilex™ 7 E-tile devices only. dr_25g_to_10g_htile Switches the data rate of the Ethernet MAC from 25G to 10G. Use for H-tile devices only dr_10g_to_25g_etile Switches the data rate of the Ethernet MAC from 10G to 25G. Use for the Stratix® 10 E-tile and Intel® Agilex™ 7 E-tile devices only. dr_25g_to_10g_htile Switches the data rate of the Ethernet MAC from 10G to 25G. Use for H-tile devices only.
