You can enable compression when creating programming files from the Convert
Programming Files dialog box. To enable compression, perform the following steps:
1. On the File menu, click Convert Programming Files.
2. Under Output programming file, select your desired file type from the
3. If you select Programmer Object File (.pof), you must specify the configuration
4. Under Input files to convert, select SOF Data.
5. Click Add File to browse to the Cyclone IV device SRAM object files (.sof).
6. In the Convert Programming Files dialog box, select the .pof you added to SOF
7. In the SOF File Properties dialog box, turn on the Compression option.
When multiple Cyclone IV devices are cascaded, you can selectively enable the
compression feature for each device in the chain.
Cyclone IV devices. The first device has compression enabled and receives
compressed bitstream from the configuration device. The second device has the
compression feature disabled and receives uncompressed data. You can generate
programming files for this setup in the Convert Programming Files dialog box.
