This chapter describes how to activate and use the error detection cyclic redundancy
check (CRC) feature when your Arria
from configuration errors caused by CRC errors.
In critical applications such as avionics, telecommunications, system control, and
military applications, it is important to be able to do the following:

■
The error detection CRC feature is provided in the Quartus
version 9.1 for Arria II GX devices and version 10.1 for Arria II GZ devices.
Using the error detection CRC feature on Arria II devices has no impact on fitting or
performance.

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 function to calculate 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 devices are
successfully configured and in user mode, the error detection CRC feature ensures the
integrity of the configuration data.
Confirm that the configuration data stored in an Arria II device is correct.
Alert the system to the occurrence of a configuration error.
