1.4. Enable Enhanced Decompression

Enhanced compression (and decompression) can reduce the size of your bitstream at the expense of greater resources use.
Important: Do not use enhanced compression with bitstream encryption.

Enhanced compression is available for Stratix® V devices. Additionally, you can also use enhanced compression with double-compression.

You can generate a bitstream with enhanced compression in one of two ways:

  • In the Convert Programming Files dialog box under the properties of a Partial-Masked SRAM Object File ( .pmsf)
  • From the command line with this command:
    quartus_cpf -c -o enhanced_bitstream_compression=on <input_filename>.pmsf <output_filename>.rbf
Note: Enhanced compression uses the same CD Ratio setting as a plain, uncompressed bitstream.
