Push-Button

Switches (SW0 -

SW0 – SW3 are momentary-contact push-button switches and are used to

provide stimulus to designs in the Stratix II device. See Figure 2–2. Each

switch is connected to a Stratix II general-purpose I/O pin with a pull-up

resistor as shown in Table 2–3. Each Stratix II device pin will see a logic 0

when its corresponding switch is pressed.

Individual LEDs

This Nios development board provides eight individual LEDs connected

to the Stratix II device. See Figure 2–2. D0 – D7 are connected to general

purpose I/O pins on the Stratix II device as shown in Ta bl e 2 –4 . When the

Stratix II pin drives logic 1, the corresponding LED turns on.
