.jic generation causes "Size of file(s) in EPCQ64 exceeds memory capacity"

I'm trying to create a .jic file so I can use the serial flash loader to program an Arria V (5AGTFD7K3F40I3).

The design is literally a GND tie and two pins. Not exactly a large design. Yet, the .sof file is 22MB(!).

I go to "Convert Programming File". I set the "Configuration device" for EPCQ64. I set up the serial flash loader for the 5AGTFD7K3. I the add the .sof file to the SOF data page. I press "Generate" and wind up with this dialog box message:

"Size of file(s) in EPCQ64 exceeds memory capacity"

Yeah, I guess 22 Megabytes is a touch bigger than an EPCQ64. It's also a touch bigger than an EPCS256, so ...

Presumably, I'm missing an option checkbox of "Don't generate enormous amounts of useless data" of some form. I'm on Quartus II 13.0 sp1 on Windows 7.

Any advice on where to start looking?

Thanks.

    According to the datasheet (http://www.altera.com/literature/hb/arria-v/av_51002.pdf), page 56, the configuration data for this FPGA is 185,915,648 bits, so your file size seem right. You should enable file compression to fit it in your configuration component. It's strange, I thought it was enabled by default.

    Compression is not really enabled by default.

    Thanks for the pointer. There are, annoyingly, two compression checkboxes.

    The one that seems to work is in the "Properties" dialog box when you select the .sof file in the "Convert Programming File" window. It's the same place where encyptions stuff is set up and specified.

    The other one is in "Assignments -> Device... -> Device and Pin Options..." and doesn't seem to do ... well ... anything.

    Thanks.

    That's right, I also notced that in Quartus 12.1.

    "Properties" dialog box when you select the .sof file in the "Convert Programming File" window is working and "Assignments -> Device... -> Device and Pin Options..." is not.
