The PowerPlay Power Analyzer generates the following reports based on the settings selected in the PowerPlay Power Analyzer Settings page:
Summarizes the following information about the power analysis performed, including the estimated total thermal power consumption of the design. The report also includes a confidence metric that reflects the overall quality of the data sources for the signal activities used in the power analysis.
Reports the settings used in the power analysis. These are as established on the PowerPlay Power Analyzer Settings and Operating Settings and Conditions pages. The report contains the following information:
Reports nodes that indicate an indeterminate toggle rate and lists the reason the node was reported.
Reports the output files, if any, produced by the PowerPlay Power Analyzer.
Lists the simulation files read, including the file ID, file name, file type, entity, VCD start time, VCD end time, the unknown %, and toggle %.
Reports the operating conditions used during power analysis performed using the PowerPlay Power Analyzer. This report appears only if your design targets a MAX II device family for compilation. The report contains the following information:
If you implemented a cooling solution that includes a heat sink, the report can contain the following categories:
Reports the total thermal power by block type, the block thermal dynamic power, the block thermal static power, and the routing thermal dynamic power for each block in the design.
Reports the total thermal power by block type, the block thermal dynamic power, the block thermal static power, the routing thermal dynamic power, and the block average toggle rate for each block in the design.
Reports the total thermal power by hierarchy, the block thermal dynamic power, the block thermal static power, the routing thermal dynamic power, and the full hierarchy name for each node in the design.
Reports the name of the clock domains, clock frequencies, and total core dynamic power for each clock domain.
If the design contains clock domains whose frequency is unspecified by a constraint, the Clock Frequency is reported as "Unspecified."
All combinational logic is reported as No clock domain and with a frequency of 0 mhz.
Reports the total current drawn, the dynamic current drawn, and the static current drawn for each voltage supply in the design. For supported device families the report also lists the minimum specification power supply required for each voltage supply.
Reports the VCCIO voltage, the total current drawn, the dynamic current drawn, and the static current drawn for each I/O bank in the design.
Reports the total current drawn, the dynamic current drawn, the static current drawn, and the minimum power supply current for each VCCIO voltage in the design.
Reports the VCCPD voltage, the total current drawn, the dynamic current drawn, and the static current drawn for each I/O bank in the design.
Reports the total current drawn, the dynamic current drawn, the static current drawn, and the minimum power supply current for each VCCPD voltage in the design.
Reports the signal data sources and associated signal types the PowerPlay Power Analyzer uses when performing the power analysis. The following are possible data sources, listed in descending order of accuracy:
The report lists the number of each of the above data sources used for each type of signal (pin, registered, and combinational), for both toggle rate and static probability data.
For data generated by a simulator (Signal Activity File (.saf) and Value Change Dump File (.vcd)), the summary also lists the percentage of nodes that toggled during the simulation, and the average percentage of time that nodes were in an unknown simulation state (a high-quality simulation is characterized by a high percentage of nodes in an unknown state for a lower percentage of simulation time).
Reports the toggle rates and static probabilities used by the PowerPlay Power Analyzer for all pins and signals with fan-out. For each signal, this report lists the signal type, the toggle rate, the data source for the toggle rate, the static probability, and the data source for the static probability.
This report appears only if you turn on Write signal activities to report file on the PowerPlay Power Analyzer Settings page.
By default, all signal activities are reported; for large designs, you may want to turn off this option, because of the large number of signals present. You can still specify that signal activities for individual nodes or entities be reported, by assigning an ON value to those nodes for the Power Analyzer Report Signal Activity assignment in the Assignment Editor.
Reports messages generated by the PowerPlay Power Analyzer during power analysis. The PowerPlay Analyzer generates info, warning, and error messages that report on conditions observed during the power analysis.
