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.
