Creating an SPI Serial Flash PROM File

The following steps describe how to format an FPGA bitstream for an SPI Serial Flash
PROM.

Setting the Configuration Clock Rate

The FPGA supports a 12 MHz configuration clock rate when connected to an M25P16 SPI
serial Flash. Set the Properties for Generate Programming File so that the
Configuration Rate is 12, as shown in
Configuration Bitstream File" in the FPGA Configuration Options chapter for a
more detailed description.
Regenerate the FPGA bitstream programming file with the new settings.
