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 devices offer on-chip circuitry for automated checking of single
event upset (SEU) detection. FPGA devices that operate 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 check (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.
