Use the data in Table 9–8 to estimate the file size before design compilation. Different
configuration file formats, such as a hexidecimal (.hex) or tabular text file (.ttf) format,
have different file sizes. For the different types of configuration file and file sizes, refer
to the Quartus II software. However, for a specific version of the Quartus II software,
any design targeted for the same device has the same uncompressed configuration file
size. If you are using compression, the file size can vary after each compilation
because the compression ratio depends on your design.
f For more information about setting device configuration options or creating
configuration files, refer to the Device Configuration Options and Configuration File
Formats chapters in volume 2 of the Configuration Handbook.
Fast Passive Parallel Configuration
FPP configuration in Arria II devices is designed to meet the continuously increasing
demand for faster configuration times. Arria II devices are designed with the
capability of receiving byte-wide configuration data per clock cycle.
You can perform FPP configuration of Arria II devices using an intelligent host such
as a MAX II device or microprocessor.
FPP Configuration Using a MAX II Device as an External Host
FPP configuration using an external host provides the fastest method to configure
Arria II devices. In this configuration scheme, you can use a MAX II device or
microprocessor as an intelligent host that controls the transfer of configuration data
from a storage device, such as flash memory, to the target Arria II device. You can
store configuration data in .rbf, .hex, or .ttf format. When using the MAX II device or
microprocessor as an intelligent host, a design that controls the configuration process,
such as fetching the data from flash memory and sending it to the device, must be
stored in the MAX II device or microprocessor.
