Power Calculation Methodology
This section describes a simplified method to estimate power consumption of an application. For
more accurate and detailed power estimations, use the SmartPower tool in Actel Libero IDE
software.
The power calculation methodology described below uses the following variables:
•
•
•
•
•
•
•
•
The number of PLLs as well as the number and the frequency of each output clock
generated
The number of combinatorial and sequential cells used in the design
The internal clock frequencies
The number and the standard of I/O pins used in the design
The number of RAM blocks used in the design
Toggle rates of I/O pins as well as VersaTiles—guidelines are provided in
page
Enable rates of output buffers—guidelines are provided for typical applications in
