Device Selection Section
1. Select the Family/Device using the pull-down list.
2. Select your device from the Available Devices pull-down list.
3. Select your desired power rail configuration from the Power Rail Configuration pull-down list.
The pull-down selections are based on examples from the pin connection guidelines for the device. Select
the closest one to your design, and use it as a basis for entering your design data. Refer to the pin
connection guidelines for your device on the Altera website.
The tool updates the list of power rails and the contents in the power rail configuration sections based on
your selections.

Power Rail Data and Configuration Section
This section of the application is divided into two areas. Area 1 is for the device power rail information,
and Area 2 is for the power rail configuration.
1. Enter the power supply voltage in the Voltage column for each power rail listed in Area 1 by selecting
a value from the pull-down menu, or by manually entering your own value.
Note: You must enter the total current consumption of related power rails before you can use the
system decoupling function.
You can optionally adjust the recommended number up or down slightly based on knowledge of the
intended application.
2. Enter the current consumption in the I max column for each power rail.
The earliest data from the Altera PowerPlay Early Power Estimator (EPE) can provide good values for
the current entries. The EPE delivers bulk data for the transceiver channels. Each bank of transceiver
channels should be assigned the total EPE value divided by the number of banks. Later in the design
cycle, the Quartus II Power Play Power Analyzer (PPPA) can derive much better data for each bank
rail.
3. Setup your device power sharing scheme in Area 2.
