edge. The switches are labeled SW7 through SW0. Switch SW7 is the left-most switch, and
SW0 is the right-most switch. The switches connect to an associated FPGA pin, as shown in
Table
Table 4-1: Slider Switch Connections
When in the UP or ON position, a switch connects the FPGA pin to V
When DOWN or in the OFF position, the switch connects the FPGA pin to ground, a logic
Low. The switches typically exhibit about 2 ms of mechanical bounce and there is no active
debouncing circuitry, although such circuitry could easily be added to the FPGA design
programmed on the board. A 4.7KΩ series resistor provides nominal input protection.
The Spartan-3 Starter Kit board has four momentary-contact push button switches,
indicated as
board, toward the right edge. The switches are labeled BTN3 through BTN0. Push button
switch BTN3 is the left-most switch, BTN0 the right-most switch. The push button
switches connect to an associated FPGA pin, as shown in
appears in
Table 4-2: Push Button Switch Connections
Pressing a push button generates a logic High on the associated FPGA pin. Again, there is
no active debouncing circuitry on the push button.
The left-most button, BTN3, is also the default User Reset pin. BTN3 electrically behaves
identically to the other push buttons. However, when applicable, BTN3 resets the
provided reference designs.
