Configuration Files

There are two types of configuration bit stream formats for different configuration schemes:

  • PS and FPP—Raw Binary File (.rbf)
  • AS—Raw Programming Data File (.rpd)

The .rpd file size follows the Intel configuration devices capacity. However, the actual configuration bit stream size for .rpd file is the same as .rbf file.

Table 54.  Configuration Bit Stream Sizes for Intel® Cyclone® 10 GX Devices

Use this table to estimate the file size before design compilation. Different configuration file formats, such as a hexadecimal file (.hex) or tabular text file (.ttf) format, have different file sizes.

For the different types of configuration file and file sizes, refer to the Intel® Quartus® Prime software. However, for a specific version of the Intel® Quartus® Prime software, any design targeted for the same device has the same uncompressed configuration file size.

I/O configuration shift register (IOCSR) is a long shift register that facilitates the device I/O peripheral settings. The IOCSR bit stream is part of the uncompressed configuration bit stream, and it is specifically for the Configuration via Protocol (CvP) feature.

Uncompressed configuration bit stream sizes are subject to change for improvements and optimizations in the configuration algorithm. This table shows the estimated configuration bit stream sizes. Refer to the .rbf file generated in the Intel® Quartus® Prime software for the actual bit stream size.
