Set Up Required for Chip Use

1. Evaluation Board Setup

Each Xizhi chip is shipped with an optional evaluation board (if requested at purchase).

1. Place the evaluation board in an ESD-protected workstation.

2. Insert the chip into the designated socket, ensuring correct orientation.

3. Connect the board to your host PC via the provided USB-C or PCIe interface.

2. Software & Driver Installation

• Download the latest drivers and software development kit (SDK) from the Xizhi Support Portal.

• Install drivers before connecting the evaluation board.

• Confirm installation by checking device recognition in your operating system’s hardware manager.

3. Recommended Test Conditions

• Ambient temperature: 20–25 °C

• Power supply: Low-noise, regulated, ripple < 1 mV

• Signal integrity: Use shielded coaxial cables for high-frequency tests

• Thermal management: For long test runs, ensure active cooling of the evaluation board

4. Data Collection Best Practices

• Use Xizhi SDK logging functions to capture raw performance metrics.

• Record environmental parameters (temperature, humidity, equipment model).

• Store logs in a secure server with batch and chip serial number for traceability.

Troubleshooting

• Device not recognized: Reinstall drivers and restart the host PC.

• Unexpected power draw: Check for socket misalignment.

• Data inconsistency: Verify clock synchronization across instruments.
