Power Reports
This section explains what you can expect to see in a power report. Power reports have a .pwr extension.
There are three types of power reports:
- “Standard Reports” (the default)
- “Detailed Reports” (the report generated when you run the “-v (Verbose Report)” command line option)
Standard Reports
A standard report contains the following:
- A report header specifying:
- The Power Summary, which gives the power and current totals as well as other summary information.
- The Thermal Summary, which consists of:
- A Decoupling Network Summary, which contains capacitance values, recommendations, and a total for each voltage source broken down in individual capacitance ranges.
- A footer containing the analysis completion date and time.
Detailed Reports
A detailed power report includes all of the information in a standard power report, plus power details listed for logic, signals, clocks, inputs, and outputs of the design.
Advanced Reports
An advanced report includes all the information in a standard report, plus the following information:
- The maximum power that can be dissipated under the specified package, ambient temperature, and cooling conditions
- Heatsink and glue combination
- An upper limit on the junction temperature that the device can withstand without breaching recommended limits
- Power details, including individual elements by type
- I/O bank details for the decoupling network
- Element name, the number of loads, the capacitive loading, the capacitance of the item, the frequency, the power, and the current
Note: The number of loads is reported only for signals. The capacitive loading is reported only for outputs. If the capacitance is zero, and there is a non-zero frequency on an item, the power is shown to be "~0", which represents a negligible amount of power.
