Demonstration Setup, File Locations, and Instructions
Transceiver Loopback Test Demo:
 Project directory: sfp_hsmb_s4gx_pcie_xcvr_loopback_6p25Gbps_restored
 Bit Stream used: hsmc_loopback.sof
 SFP HSMC Setup
 Insert SFP modules with loopback connectors into SFP ports 0-3 on the SFP HSMC board
 Set SW5 switches on the SFP HSMC all to the “0” position
 Stratix IV GX FPGA Development Kit Setup
 Set SW3 switches 1-3 & 5-8 in the “down” position.
 Set SW3 switch 4 in the “up” position
 Set SW4 switches 1,2,4 in the “up” position and switches 3,5,6,8 in the “down” position
 Set the rotary switch (SW2) to the 0 position
 Power on the Stratix IV GX FPGA Development Board and download the SOF file
(hsmc_loopback.sof)
 Press and release CPU reset button located on the host board to initiate the test
 Press and release PB0, enabling comma detect
 Press and release PB1 enabling channel bonding
 Press and release PB2, start transmitting PRBS data
 LED0, LED1, and LED2 should be ON and LED3 should be OFF.
 Remove one of the SFP modules or one side of a connector so that the loopback will fail. A Failure
is indicated on the Stratix IV GX FPGA Dev Kit when LED3 turns ON
 To reset the board test system, press and release the CPU reset button on the host board
 Press and release PB1 and PB2 at the same time creates an error in the transmitter data stream,
where LED3 should be ON
 Press and release, the CPU reset button on the host board and verify the results
LVDS Loopback Test Demo:
 Project directory: sfp_hsmb_s4gx_pcie_lvds_loopback_restored
 Bit Stream used: hsmc_loopback.sof
 SFP HSMC Setup
 Insert SFP modules with loopback connectors into SFP ports 4-7 on the SFP HSMC board
 Set SW4 switches on the SFP HSMC all to the “1” position
 Stratix IV GX FPGA Development Kit Setup
 Set SW3 switches 1-4 & 6-8 in the “down” position.
 Set SW3 switch 5 in the “up” position
 Set SW4 switches 1,2,4 in the “up” position and switches 3,5,6,8 in the “down” position
