Program Push Button/DONE Indicator LED
The Spartan-3 Starter Kit Board includes two FPGA configuration functions, located near
the VGA connector and the AC power input connector, as shown in
Figure 9-1
. The PROG
push button, shown as
in
Figure 9-1
, drives the FPGA’s PROG_B programming pin.
When pressed, the PROG push button forces the FPGA to reconfigure and reload it
configuration data.
The DONE LED, shown as
in
Figure 9-1
, connects to the FPGA’s DONE pin and lights
up when the FPGA is successfully configured.
Slave Parallel
<0:1:1>
Another device connected to the B1 expansion connector
provides parallel data and clock to load the FPGA.
JTAG
<1:0:1>
The FPGA waits for configuration via the four-wire JTAG
interface.
