7–2 Chapter 7: Power Measurement
Power Design Example
Cyclone III FPGA Development Kit User Guide September 2010 Altera Corporation
The LEDs in Table 7–2 indicate the power-state values of the design example as
User_PB1 advances frequency.
The LEDs in Table 7–3 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 7–3) controls the number of I/O pins used. Each resource
increment adds 8 additional I/O pins (Table 7–3). Similarly, the overall design
frequency (Table 7–2) sets the toggle frequency of these I/O pins.
