15. Check Verify . Unchecking Verify reduces programming time but the iMPACT
software can only guarantee correct programming for a verified PROM.
16. Check Erase Before Programming . Unchecking the Erase option reduces
programming time. However, Xilinx recommends erasing the PROM when
downloading a new FPGA bitstream.
17. Click OK .
18. The iMPACT software indicates successful programming, as shown in
Figure 12-18 .The FPGA is configured with the new programming file.
