Once you have the device displayed you can examine inputs and outputs with the mouse arrow. You can see which macrocells are involved and what the power setting and slew rate are for the Input/Output. The name and pin number of each pin is located next to the pin. Input and output pins are distinguished by different colors, depending on the color scheme you have set. Pins with no connection show only the pin number; the pin is left white.
To examine the Power and Slew Rate Settings for an Input/Output, place the mouse arrow over the pin. The settings will appear in a pop-up box appears with the settings listed.
With the mouse click once on the pin. If the pin is an input pin, a red line will go to each an every macrocell the signal is connected to. If the pin is an output pin, a line will go to the macrocell which produces the output signal.
