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.
