For Arria II GX devices, the error detection CRC feature is provided in the Quartus
software starting with version 9.0.
Using the error detection CRC feature on Arria II GX devices has no impact on fitting
or performance.
For more information about the CRC feature, refer to
Detection and Recovery using CRC in Altera FPGA
Error detection determines if the data received through a medium is corrupted during
transmission. To accomplish this, the transmitter uses a function to calculate a
checksum value for the data and appends the checksum to the original data frame.
The receiver uses the same calculation methodology to generate a checksum for the
received data frame and compares the received checksum to the transmitted
checksum. If the two checksum values are equal, the received data frame is correct
and no data corruption occurred during transmission or storage.
The error detection CRC feature uses the same concept. When Arria II GX devices are
successfully configured and are in user mode, the error detection CRC feature ensures
the integrity of the configuration data.
