Microchip Technology Libero SoC v2022.1 User Manual

Introduction

SmartPower is a power-analysis tool that allows you to visualize power consumption and potential power
consumption problems globally and in-depth within your design, so you can make adjustments – when possible
– to reduce power.
SmartPower provides a detailed and accurate way to analyze designs for Microchip SoC FPGAs, from top-level
summaries to deep-down specific functions within the design, such as gates, nets, I/Os, memories, clock domains,
blocks, and power supply rails.
You can analyze the hierarchy of block instances and specific instances within a hierarchy, and each can be
organized in various ways to show the respective power consumption of the component pieces.
SmartPower also analyzes power by functional modes, such as Active, Flash*Freeze, Shutdown, Sleep, or Static,
depending on the specific FPGA family used. You can also create custom modes that may have been created in the
design. Custom modes can also be used for testing "what if" potential operating modes.
SmartPower has a unique feature that allows you to create test scenario profiles. A profile enables you to create sets
of operational modes, so you can understand the average power consumed by this combination of functional modes.
An example may be a combination of Active, Sleep, and Static modes — as would be used over time in an actual
application.
SmartPower generates detailed hierarchical reports of the power consumption of a design for easy evaluation. This
enables you to locate the power consumption source and take appropriate action to reduce the power if possible.
SmartPower supports use of files in the Value-Change Dump (VCD) format, as specified in the IEEE
generated by the simulation runs. Support for this format lets you generate switching activity information from
ModelSim or other simulators, and then use the switching activity-over-time results to evaluate average and peak
power consumption for your design.
