Introduction
The Terasic USB Blaster Download Cable(UBT) interfaces a USB port on a host computer to an FPGA mounted on a printed circuit board. The cable sends configuration data from the host computer to a standard 10-pin header connected to the FPGA. You can use the UBT to iteratively download configuration data to a system during prototyping or to program data into the system during production.
