To estimate and validate the power and thermal performance of your AFU design using the Intel Programmable Acceleration Card with Intel Arria 10 GX FPGA, you can follow these steps outlined in the user guide:
1. **Power Specification:** Ensure that the total board power does not exceed 66W and FPGA power does not exceed 45W to prevent unexpected shutdowns by the Board Management Controller.
2. **Tools Requirements:** You will need various software tools like Intel Acceleration Stack for Development, BWtoolkit, AFU Design, Tcl script, Early Power Estimator for Intel Arria 10 devices, and the Intel FPGA PAC Power Estimator Sheet. Hardware requirements include the Intel FPGA PAC, Micro-USB cable, and a target server for Intel FPGA PAC.
3. **Using the Board Management Controller:** The Board Management Controller monitors and controls power events, and in case of overheating or excessive current draw, it triggers an auto-shutdown to protect the board. You must power cycle the server to restore power after an auto-shutdown event.
4. **Monitoring Sensors:** You can use tools like fpgainfo and BWMonitor to gather temperature and power sensor data from the Board Management Controller for monitoring and analysis.
5. **Power Measurement Flow:** To evaluate the power for your AFU design, capture metrics like total board power, FPGA temperature, static power, and worst-case static power. Use these metrics with the Intel FPGA PAC Power Estimator Sheet to verify if your AFU design meets the power specification.
6. **Estimating Worst-Case Core Static Power:** Follow steps to estimate the worst-case static power by using the Early Power Estimator tool and inputting parameters like Junction Temp and Power Characteristics.
By following these steps and utilizing the recommended tools, you can estimate and validate the power and thermal performance of your AFU design effectively with the Intel Programmable Acceleration Card with Intel Arria 10 GX FPGA.
