SmartPower User Guide
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® 1364 standard,
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.
SmartPower supports SmartFusion®2, IGLOO®2, RTG4™, PolarFire®, and PolarFire SoC devices.

2.1.2 Breakdown
Displays a breakdown of power consumption in the design. A drop-down list allows you to view the power breakdown
by type of component, voltage rail, or clock domain.
2.1.2.1 Show
Displays power usage as a chart or as a grid.
When you select By Type from the drop-down list, the Summary tab displays a breakdown of the design's power
usage by the following types:
• Net
• Gate
• I/O
• Memory
• Core Static
• Banks Static
• Analog (for Fusion Designs)
Any static power used by instances of a component in a design will be included in the appropriate category. As a
result, the sum of the power in breakdown by type will be equal to the total static and dynamic power consumption of
the design. Percentages displayed are fractions of the total power. Global nets are included in the net power types.
To obtain the power of a clock, select breakdown by clock domain.
When you select By Rail from the drop-down list, the Summary tab displays a breakdown of the power usage by the
rail that the power is drawn from and a breakdown for the current usage. The power, voltage, and current drawn for
each rail are displayed.
When you select By Clock Domain from the drop-down list, the Summary tab displays a breakdown of the power
usage by the clock domain that the power is drawn from. For each clock domain, the power and percentage of power
drawn are displayed. Dynamic power is accounted for in breakdown by clock, but static power is not associated with
any clock.
By Mode is available only when a scenario is selected. When you select By Mode in the Modes and Scenarios
toolbar, the Summary tab shows power consumption, duration, and power duration weight by mode.
After you select By Type, By Rail, By Mode, or By Clock Domain, you can customize the columns in the grid by
right-clicking the column headers. To exclude a column, remove its check mark from the right-click menu. Right-click
a column header to set the column default size for the selected column or for all columns, and then sort the values in

The Domains tab lists existing domains along with their corresponding clock and data frequencies and probability
data for clock domains and sets of pins. In this tab, you can add, edit, or remove domains or sets of pins, and change
the clock and/or data frequency for a selected domain.
When you start SmartPower for the first time, it automatically initializes frequencies from SmartTime with a default
data toggle rate of 10%. However, if you update your timing constraints in SmartTime, you can use the Initialize
Frequencies and Probabilities dialog box to update SmartPower with new frequencies from SmartTime. If you do not
have timing constraints in SmartTime, you can initialize clock and data frequencies manually by directly editing the
Domains tab grid or using the Initialize Frequencies and Probabilities dialog box.
If you import a VCD file, the Domains tab shows the average clock and data frequencies for each clock domain and
input set. This average is calculated using VCD information.
Note: If you change a clock or data frequency in the Domains tab, it impacts only nets that use the default
estimation source. Nets use the default estimation source when they have not been manually set to a specific
frequency in the Frequencies tab, and when they have not been set by importing a VCD file. To see explicitly the list
of nets using the default estimation source, refer to the Frequencies tab.

2.4.2 Average Frequencies
Displays the average frequency of all pins displayed in the grid.
Average frequencies are useful when you import a VCD file. Because these files allow you to specify the frequency of
each pin individually, it is useful to know the average clock pin or data pin frequency for a particular clock domain.
If you did not specify a frequency annotation for any clock pin in this clock domain, the average value is equal to the
default clock frequency of the clock domain. If you set one or several clock pins, SmartPower takes those annotations
to compute an average value.
If you did not specify a frequency annotation for any data pin in this clock domain, the average value is equal to
the default data frequency of the clock domain. If you set one or several data pins, SmartPower considers these
annotations into account to compute an average value.
2.4.3 Annotation Statistics
VCD import: displays the percentage of pins with frequencies imported from the *.vcd file.
Manual annotation: displays the percentage of pins with manually-annotated frequencies.
Fixed values: displays the percentage of pins with default frequency.
2.5 Probabilities Tab
The Probabilities tab displays the drivers, nets, types, polarity, rates, and source for each pin. Use the Probabilities
tab to control the probabilities for all pins.
•Bidirectional and Tristate I/Os: controls the output probability of each tristate and bidirectional I/O. The
probability is the percentage of time that the I/O is used as an output. You can change the default value and set
a specific value for each bidirectional or tristate I/O.
•Memories: controls the read cycle probability or the write cycle probability of a memory block. The probability is
the percentage of time that a memory block will be used in a read cycle or a write cycle. You can change the
default value and set a specific value for each enable pin of each memory block available in the design. If an
enable pin is active low, assign it a probability of 0% to completely enable the I/O or the memory block, or 100%
to disable it completely.

In designs with a cascaded memory, all memory enable pins are shown in the Probabilities tab. To simulate real-
world power consumption, selectively enable only some memory enable pins, as specified in the memory cascading
structure.
• For purely vertical cascading, enable the pins that belong to one RAM block.
• For purely horizontal cascading, enable all pins belonging to all RAM blocks of the cascaded memory.
To find which RAM block corresponds to which pin, cross-probe with the MVN NetlistViewer.
The Driver box allows you to filter the list of drivers based on the criteria entered. Enter text in the filter box, and click
Set to apply this text as a filter. Use the * character as a wildcard.

•Operating Conditions: allows you to set the operating conditions: Best, Typical, or Worst. The actual voltage
and temperature of a given operating condition is defined by the operating condition range selected for the
current design (COM, IND, MIL, Auto, TGrade1, TGrade2, and Custom). For SmartPower, unlike SmartTime, the
worst voltage is the upper bound of the range. That is, higher (worst-case) power comes from higher voltage,
while higher voltage results in best-case speed.
Note: Worst-case and best-case calculations are available only for certain families and devices.
•Frequency Preferences: sets unit preferences for frequency: Hz, KHz, MHz.
•Power Preferences: sets unit preferences for power: W, mW, or uW.
