Configuration Options
The JTAG chain can be used to program the FPGA and access the FPGA for hardware and
software debug.
The JTAG connector (USB Mini-B J10) allows a host computer to download bitstreams to
the FPGA using the iMPACT software tool, and also allows debug tools such as the
ChipScope™ Pro Analyzer tool or a software debugger to access the FPGA.
The iMPACT software tool can also program the SPI x4 flash or the BPI flash via the USB
J10 connection. iMPACT can download a temporary design to the FPGA through the
JTAG. This provides a connection within the FPGA from the FPGA's JTAG port to the
FPGA's SPI or BPI interface. Through the connection made by the temporary design in the
FPGA, iMPACT can indirectly program the SPI flash or BPI flash from the JTAG USB J10
connector.
