Programming the FPGA, CPLD, or Platform Flash PROM via USB R
If the original FPGA configuration file used the default StartUp clock source, CCLK,
iMPACT issues the warning message shown in Figure 4-7 . This message can be safely
ignored. When downloading via JTAG, the iMPACT software must change the StartUP
clock source to use the TCK JTAG clock source.
To start programming the FPGA, right-click the FPGA and select Program. The iMPACT
software reports status during programming process. Direct programming to the FPGA
takes a few seconds to less than a minute, depending on the speed of the PC’s USB port and
the iMPACT settings.
When the FPGA successfully programs, the iMPACT software indicates success, as shown
in Figure 4-9 . The FPGA application is now executing on the board and the DONE pin LED
(see Figure 4-2 ) lights up.
