4. Measuring Power on the
Cyclone III Starter Board
Introduction
One of the main features of the Cyclone ? III device is its low power
consumption. You can measure the power of the 3C25 device on the
Cyclone III starter board under various conditions with an example
design provided with the kit.
The power example design allows you to control the amount of logic
utilized in the FPGA, the clock frequency, the number of I/Os being used,
and measure the effect on the power to the Cyclone III device. Because the
Cyclone III starter board has only four buttons and four LEDs, interaction
with the board is minimal as defined below.
Table 4–1 describes the functionality of the four input buttons that control
the power example design.
