Introduction to Power Analysis and Optimization

Welcome to this online training about power analysis and optimization for Intel Arria 10 and Stratix 10 devices. This training, led by Steve, covers essential information on performing power analysis and optimizing power usage throughout the design process.

Performing a Power Analysis

To perform a power analysis, it's crucial to understand static and dynamic power usage. Tools like the Early Power Estimator spreadsheet (EPE) and the Intel Quartus Prime Power Analyzer are used for detailed analysis at different stages of the design process.

Early Power Estimator Spreadsheet (EPE)

The EPE is a primary tool for quick power usage analysis at any design stage. It provides essential insights before diving into more detailed analysis with the Power Analyzer.

Intel Quartus Prime Power Analyzer

For a more accurate power analysis later in the design process, the Power Analyzer is used. It requires simulation information and other input data to configure for detailed analysis.

Optimizing a Design for Power

Optimizing power usage is critical, and you'll learn about power-driven compilation and options available in the Intel Quartus Prime software to achieve this.

Power-Driven Compilation

Power-driven compilation helps optimize power usage by utilizing specific options available in the Intel Quartus Prime software.

Low Power Design Guidelines

Following low power design guidelines is essential for reducing power usage throughout a design, ensuring power requirements are met efficiently.

Smart Voltage ID Feature

Devices supporting the Smart VID feature can reduce core voltage below the nominal value while maintaining performance, resulting in significant power savings.

Implementing Smart VID in Intel Arria 10 Devices

To implement Smart VID in Intel Arria 10 devices, the Smart VID controller IP must be added to the design, along with a temperature sensor IP and a voltage regulator control system.

Implementing Smart VID in Intel Stratix 10 Devices

In Intel Stratix 10 devices, the Smart VID feature is handled by the Secure Device Manager block, simplifying the implementation process. An external PMBus-controlled voltage regulator is required.

Conclusion

Power analysis and optimization are crucial for efficient FPGA design. Utilizing tools like the EPE and Power Analyzer, and implementing features like Smart VID, can significantly reduce power usage while maintaining performance.
