Troubleshooting Chip Overheating During Lab Testing

If your Xizhi chip is overheating during testing, follow these steps to identify and resolve the issue.

---

1. Confirm Basic Setup

• Verify the chip model and batch number.

• Ensure the ambient lab temperature is within the recommended range (20–25°C).

• Check that the chip is mounted correctly with a secure heatsink or cooling solution.

---

2. Run Thermal Diagnostics

Use the built-in diagnostic tool to monitor chip temperature:

xizhi_diag --thermal

• Record the maximum temperature observed (°C).

• Note the duration before overheating occurs.

3. Review Power and Cooling

• Power Supply: Ensure your regulated power supply matches the voltage/current specifications.

• Cooling Method: Check fan or liquid cooling efficiency, and replace thermal paste if needed.

4. If the Issue Persists

Please contact Xizhi Support with the following details:

• Chip model + batch number

• Max temperature reached and time to overheating

• Cooling setup and lab conditions

• Diagnostic output from xizhi_diag --thermal

Our engineering team will guide you through advanced checks or arrange further analysis if a hardware fault is suspected.
