1.3.1.2.1. Enabling Bitstream Encryption or Compression for Intel® Arria® 10 and Intel® Cyclone® 10 GX Devices

You can optionally enable bitstream file encryption that requires a user-defined 256-bit security key to access the configuration bitstream. Alternatively, you can enable bitstream compression to reduces the size of your programming file to minimize file transfer and storage requirements. The compression reduces configuration file size by 30% to 55% (depending on the design). File compression and encryption options are mutually exclusive for Intel® Arria® 10 and Intel® Cyclone® 10 GX devices.

Follow these steps to enable bitstream file compression or encryption for Intel® Arria® 10 and Intel® Cyclone® 10 GX devices:

  1. Generate a .jic file for flash programming, as this document describes.
  2. In the Convert Programming File dialog box, select the .sof file under Input files to convert.
  3. Click the Properties button. The SOF File Properties: Bitstream Encryption dialog box appears.

  4. To enable compression, turn on the Compression option. All encryption options disable as these options are mutually exclusive.
  5. To enable bitstream file encryption:
    1. Turn off the Compression option.
    2. Turn on the Generate encrypted bitstream option.
    3. Specify options for programming file key decryption, and Security Options, as Compression and Encryption Settings (Convert Programming File) describes.
  6. Click OK.
