Chapter 10: SEU Mitigation in Arria II Devices
Recovering From CRC Errors
Recovering From CRC Errors
The system that the Arria II device resides in must control device reconfiguration.
After detecting an error on the CRC_ERROR pin, strobing the nCONFIG signal low directs
the system to perform the reconfiguration at a time when it is safe for the system to
reconfigure the device.
When the data bit is rewritten with the correct value by reconfiguring the device, the
device functions correctly.
While soft errors are uncommon in Altera® devices, certain high-reliability
applications require a design to account for these errors.
