1.7. Testing the Hardware Design Example
After you compile the Interlaken (2nd Generation) Intel® FPGA IP core design example and configure your device, you can use the System Console to program the IP core and its embedded Native PHY IP core registers.
Follow these steps to bring up the System Console and test the hardware design example:
- In the Intel® Quartus® Prime Pro Edition software, on the Tools menu, click System Debugging Tools > System Console.
- Change to the <design_example_installation_dir>example_design/hwtest directory.
- To open a connection to the JTAG master, type the following command:
source sysconsole_testbench.tcl
- You can turn on internal serial loopback mode with the following design example commands:
- stat: Prints general status info.
- sys_reset: Resets the system.
- loop_on: Turns on internal serial loopback.
Note: You don't need to run this command in Intel® Stratix® 10 H-tile device variations.
- run_example_design: Runs the design example.
Note: In Intel® Stratix® 10 H-tile device variations, you just need to run run_example_design command. The run_example_design runs the following commands in a sequence: sys_reset->loop_on->stat->gen_on->stat->gen_off.In Intel® Stratix® 10 E-tile device variations, you must run loop_on command before run_example_design command. The run_example_design runs the following commands in a sequence: sys_reset->stat->gen_on->stat->gen_off.
Note: When you select the Enable adaptation load soft IP option, the run_example_design command performs the initial adaptation calibration on RX side by running the run_load_PMA_configuration command. - You can turn off internal serial loopback mode with the following design example command:
- loop_off: Turns off internal serial loopback.
- You can program the IP core with the following additional design example commands:
- gen_on: Enables packet generator.
- gen_off: Disables packet generator.
- run_test_loop: Runs the test for <N> times for E-tile NRZ and PAM4 variations.
- clear_err: Clears all sticky error bits.
- set_test_mode <min_okt_size> <max_pkt_size> <step> <num_to_run>: Sets up test to run in a specific mode.
- get_test_mode: Prints the current test mode.
- set_burst_size <burst_size>: Sets burst size in bytes.
- get_burst_size: Prints burst size information.
The successful test prints HW_TEST:PASS message. Below is the passing criteria for a test run:- No errors for CRC32, CRC24, and checker.
- Transmitted SOPs and EOPs should be match with received.
