Bitstream Compression

I'm using a Cyclone II EP2C5 connected to a EPCS1 on my board. I want to use the Serial Flash Loader to program the EPCS1 on my board via JTAG.

I have enabled bitstream compression (Generate bitsream compression) via Assignment -> Devices, but still the SOF file is not compressed.

When compiling the project, the Assembler settings still say Compression mode is off.

Is this a bug in Quartus II or am I doing something wrong?

    Bitstream compression is an attribute of a particular programming file. For serial flash loader, the compression is set when generating jic-files under properties of imported sof-file.

    Sorry for asking, but how do I set this up? The documentation is a bit vague on exactly how. :confused:

    Ok, I got it right. Just clicked on properties after I specified the SOF file during the conversion to JIC file:D

    Thanks for your help.
