Recovering from CRC Errors

The system that MAX 10 resides in must control device reconfiguration. After detecting an error on the

CRC_ERROR pin, strobing the nCONFIG pin low directs the system to perform reconfiguration at a time

when it is safe for the system to reconfigure the MAX 10 device.

When the data bit is rewritten with the correct value by reconfiguring the device, the device functions

correctly.

While SEUs are uncommon in Altera devices, certain high-reliability applications might require a design

to account for these errors.

Configuration Data Compression

MAX 10 devices can receive compressed configuration bitstream and decompress the data in real-time

during configuration. This feature helps to reduce the configuration image size stored in the CFM.

Preliminary data indicates that compression typically reduces the configuration file size by at least 30%

depending on the design.
