Safety Warnings (Must Read)
- Do NOT hot-plug the board: Power off the FPGA carrier board and unplug the power cable before installation/removal. Hot-plug operation will directly damage the board, carrier board or connected devices.
- Take ESD Protection Measures: Release static electricity from the human body (anti-static wristband is recommended) before touching the electronic components of the product. Static electricity can cause permanent damage to precision components.
- Standard Interface Connection: Ensure the FMC slot is fully aligned with the board connector before insertion to avoid pin damage caused by violent plugging; confirm that the signal type matches the loopback mode during testing.
- Power Supply Safety: Connect power supply in strict accordance with the power supply requirements of the carrier board, ensure that the voltage is stable within the rated range, and avoid circuit burnout caused by overvoltage or reverse connection.
- Environmental Requirements: Avoid storing or using the product in places with water splashing, direct sunlight, strong electric/magnetic fields, strong vibration, or heavy dust to ensure long-term stable operation of the device.
Quick Start Guide
- Hardware Connection: Insert the Hello-FPGA-FMC-LOOP mezzanine card into the FMC HPC slot of the FPGA carrier board correctly, tighten the fixing screws to ensure the connector is fully engaged.
- Power Supply Configuration: Confirm that the FPGA carrier board is powered normally, configure VADJ voltage (1.2V/1.8V/2.5V, etc.) according to test requirements to ensure stable working voltage of the mezzanine card.
- Software Configuration: Launch Xilinx VIVADO development environment, load the board configuration file, configure loopback mode and clock parameters according to test type (DP/LA/HA/HB).
- Test & Verification: Enable IBERT tool for 25Gbps high-speed differential signal bit error rate test, or perform general-purpose signal sampling and output verification through ILA/IO function, confirm that the test results meet the standards.
