You can use the PowerPlay Power Analyzer Tool command on the
Processing menu after running Analysis & Synthesis and the Fitter
successfully. You can specify whether you want to use an input file, such as
a Signal Activity File ( .saf ) or Value Change Dump File ( .vcd ) generated by
the Quartus II Simulator or a Value Change Dump File generated by another
EDA simulation tool, to initialize toggle rates and static probabilities during
power analysis, and also whether you want the signal activities used during
power analysis written to an output file. In addition, you can specify
entity-based toggle rates and static probabilities using user assignments in
the Quartus II user interface or in the Quartus II Settings File ( .qsf ). For some
device families, the Quartus II software fills in any missing signal activity
information by analyzing the design topology and function.
