PROMGen Options

–s (PROM Size)

–spromsize1 promsize2...

This option sets the PROM size in kilobytes. The PROM size must be a power of 2. The default value is 64 kilobytes. The –s option must precede any –u, –d, or –n options.

Multiple promsize entries for the –s option indicates the PROM will be split into multiple PROM files.

Note: PROMGen PROM sizes are specified in bytes. See the –x option for more information.

–t (Template File)

–ttemplatefile.pft

The –t option specifies a template file for the user format PROM (UFP). If unspecified, the default file $XILINX/data/default.pft is used. If the UFP format is selected, the –t option is used to specify a control file.

–u (Load Upward)

–uhexaddress0 filename1 filename2...

This option loads one or more BIT files from the starting address in an upward direction. When you specify several files after this option, PROMGen concatenates the files in a daisy chain. You can load files at different addresses by specifying multiple –u options.

This option must be specified immediately before the input bitstream file.

–ver (Version)

–ver[version] hexaddress filename1.bit filename2.bit . . .

The –ver option loads .bit files from the specified hexaddress. Multiple .bit files daisychain to form a single PROM load. The daisychain is assigned to the specified version within the PROM.

Note: This option is only valid for Xilinx multi-bank PROMs.

–w (Overwrite Existing Output File)

promgen –w

The –w option overwrites an existing output file, and must be used if an output file exists. If this option is not used, PROMGen issues an error.

–x (Specify Xilinx PROM)

–xxilinx_prom1 xilinx_prom2...

The –x option specifies one or more Xilinx serial PROMs for which the PROM files are targeted. Use this option instead of the –s option if you know the Xilinx PROMs to use.

Multiple xilinx_prom entries for the –x option indicates the PROM will be split into multiple PROM files.
