3.4. Hardware Testing

The hardware design example provides the loopback test. In loopback test mode, the traffic generator sends packets to the F-Tile Serial Lite IV TX core and loopback to the RX core either internally or externally.

Figure 9. Loopback Test

To use the system console script, navigate to the ./ed_hwtest/system_console directory. Source the sliv_ftile.tcl script. The system console script provides useful commands for reading statistics and enables you to control various features in the design.

Table 10.  System Console Commands for Hardware Testing
Command Function
list_jtag Displays a list of JTAG master indexes that are connected to your board.
set_jtag <jtag master_index number> Selects the JTAG master.
  • To enable internal and external loopback, use the JTAG master index number of phy_1/phy_jtag_m JTAG node.
    For example, the JTAG master index of phy_1/phy_jtag_m JTAG node shown in the following JTAG list is 2. Type set_jtag 2 to select JTAG master index 2. Next type the enable internal or external loopback commands. 
    % list_jtag
Available JTAG Masters:
0:    /devices/<JTAG_port>/phy_0/master
1:    /devices/<JTAG_port>/phy_0/demo_jtag_m.master
2:    /device/<JTAG_port>/phy_1/phy_jtag_m.master
  • To perform commands other than internal and external loopback, use JTAG master index number of phy_0/demo_jtag_m JTAG node.
    For example, the JTAG master index of phy_0/demo_jtag_m JTAG node shown in the following JTAG list is 1. Type set_jtag 1 to select JTAG master index 1. Next type the system console command that you want to use. 
    % list_jtag
Available JTAG Masters:
0:    /devices/<JTAG_port>/phy_0/master
1:    /devices/<JTAG_port>/phy_0/demo_jtag_m.master
2:    /device/<JTAG_port>/phy_1/phy_jtag_m.master
read_error_statistic Displays the error statistics.
sl4_link_init_int_lpbk <index number> Enables TX to RX internal serial loopback within the transceiver and performs the specific transceiver calibration flow.
  • 0: Disable internal serial loopback
  • 1: Enable internal serial loopback
traffic_gen_enable Enables the traffic generator and checker.
traffic_gen_disable Disables the traffic generator and checker.
continuous_mode_en Resets the TX and RX core (MAC and PHY) and enables the traffic generator to generate continuous (single continuous data generation) traffic stream.
burst_mode_en Resets the TX and RX core (MAC and PHY) and enables the traffic generator to generate a burst (multiple burst packet data generation) traffic stream.
crc_err_inject_pulse Enables CRC error injection for all lanes.
