5–2 Chapter 5: Power Measurement

Power Design Example

Stratix III Development Kit User Guide © August 2008 Altera Corporation

The LEDs in Table 5–2 indicate the power-state values of the design example as

User_PB1 advances frequency.

The LEDs in Table 5–3 indicate the power-state values of the design example (and

number of output pins, when enabled by User_PB3) as User_PB2 advances resource

utilization.

The resource state (Table 5–3) controls the number of I/O pins used. Each resource

increment adds eight additional I/O pins (Table 5–3). Similarly, the overall design

frequency (Table 5–2) sets the toggle frequency of these I/O pins.
