How can I create a compressed configuration bitstream to take advantage of my Cyclone FPGA's on-chip decompression feature?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description Cyclone FPGAs can recieve compressed configuration data and decompress this data on the fly during configuration. This feature is enabled by generating a compressed configuration bitstream/programming file from the Quartus® II versions 2.2 SP1 and higher.

There are two ways to enable compression in Cyclone:

  1. Under Assignments -> Device -> Device & Pin Options -> General Tab, enable the check box for Generate compressed bitstream.
  2. An alternative method is to:
    1. Open File -> Convert Programming Files
    2. Select a Serial Config device (EPCS1 or EPCS4)
    3. Select Add File and add Cyclone SOF file
    4. Select the name of file you added and click on Properties
    5. Enable the Compression check box
