    Hi,

    I believe there are some misunderstandings involved with your post.

    1. The .sof file, which is used for direct JTAG configuration and as a source for AS programming file generation is never compressed.
    2. Compression can be enabled in Programming File Generator for .jic and .rpd AS programming files. It doesn't reduce .jic file size, which always reflects capacity of chosen flash device, but the non-erased file content (different from 0xFF) is reduced, also .rpd file size. Respectively flash programming time and time to load the configuration is shorter.
    3. Compression option is somehow hidden in PFG GUI under properties of the .sof file.

Yes, this is the way I got it to compress and reduce configuration time. Thanks.
