You can also enable compression when creating programming files from the Convert
Programming Files window. To do this, follow these steps:
1. On the File menu, click Convert Programming Files.
2. Select the programming file type (.pof, .sram, .hex, .hexout, .rbf, or .ttf).
3. For POF output files, select a configuration device.
4. In the Input files to convert box, select SOF Data.
5. Select Add File and add a Stratix V device .sof.
6. Select the name of the file you added to the SOF Data area and click Properties.
7. Check the Compression check box.
If you are using a serial configuration scheme, AS ×1 or PS, for multi-device
configuration, you can selectively enable the compression feature for each device in
the chain.
device has compression enabled and therefore receives compressed data from the
external host. The second Stratix V device has the compression feature disabled and
receives uncompressed data.
For FPP configuration schemes, a combination of compressed and uncompressed
configuration in the same multi-device chain is not allowed due to the difference of
the DCLK-to-DATA[] ratio.
