Document Table of Contents Data Compression

Data compression is always enabled in Arria® 10 configuration, the Quartus® Prime software generates configuration files with compressed configuration data. This compressed file reduces the storage requirements in the configuration device or flash memory, and decreases the time required to transmit the configuration bitstream to the Arria® 10 device.

Arria® 10 devices support decompression in the FPP, AS, and PS configuration schemes. Use the Arria® 10 decompression feature if you use the PS mode to reduce configuration time. The Arria® 10 decompression feature is not available in the JTAG configuration scheme.

When compression is turned on, the DCLK to DATA ratio changes accordingly based on the FPP configuration scheme selected (FPP ×8, FPP ×16, or FPP ×32). To ensure a successful configuration, the configuration controller must send the DCLK that meets the DCLK to DATA ratio.
