Xilinx Development System
The following figures show which pins to connect, depending on
your chosen FPGA device. For descriptions of each pin, see Table 3-
6and Table 3-7 of the “FPGA Design Demonstration Board” chapter.
Use Header 1 (see
) to connect the XChecker Cable to the
target system for configuring FPGAs. When configuring XC4000
FPGAs, the RST (Reset) wire is not used as shown in the following
figure.
Figure 1-11 XChecker Connections to XC4000 Device
To configure XC3000 FPGAs, the PROG wire is not used. This is
shown in the following figure. In both cases, the FPGA must be in the
Serial Slave Mode.
