Local Update Mode
Local update mode is a simplified version of the remote update. This
feature is intended for simple systems that need to load a single
application configuration immediately upon power-up without loading
the factory configuration first. Local update designs have only one
application configuration to load, so it does not require a factory
configuration to determine which application configuration to use.

Stratix GX devices offer on-chip circuitry for automated checking of
single event upset (SEU) detection. Some applications that require the
device to operate error free at high elevations or in close proximity to
earth’s North or South Pole require periodic checks to ensure continued
data integrity. The error detection cyclic redundancy code (CRC) feature
controlled by the Device & Pin Options dialog box in the Quartus II
software uses a 32-bit CRC circuit to ensure data reliability and is one of
the best options for mitigating SEU.
