1.6.1. Test Commands

This reference design provides various Tcl commands to test the Arria® 10 FPGA development board and the Dual XAUI to SFP+ HSMC board in various loopback modes.
Table 6.  TCL CommandsFormat for the TCL command test is TEST <LPBK_POINT> <BURST_SIZE> <NUM_BURSTS> .
Command Mode/Values Description
LPBK_POINT SFPP Loopback at SFP+ cable
BCMPMA Loopback at BCM8727 PMA
BCMXGXS Loopback at BCM8727 XGXS
ALTPMA Loopback at Intel serial PMA
BURST_SIZE Any integer Number of packets in the burst.
NUM_BURSTS Any number greater than 0 Specifies the intended number of bursts.
Each test generates a log file in text file format. View the log to ensure that the traffic monitor does not receive bad packets. The log also provides packet classification and statistics by the MAC TX and RX.
Note: Make sure to reset using the push buttons after each test completes.
