This chapter describes the cyclical redundancy check (CRC) error detection feature in
user mode and how to recover from soft errors.
Configuration error detection is supported in all Cyclone
Cyclone IV GX devices, Cyclone IV E devices with 1.0-V core voltage, and
Cyclone IV E devices with 1.2-V core voltage. However, user mode error detection is
only supported in Cyclone IV GX devices and Cyclone IV E devices with 1.2-V core
voltage.
Dedicated circuitry built into Cyclone IV devices consists of a CRC error detection
feature that can optionally check for a single-event upset (SEU) continuously and
automatically.
In critical applications used in the fields of avionics, telecommunications, system
control, medical, and military applications, it is important to be able to:

Using the CRC error detection feature for Cyclone IV devices does not impact fitting
or performance.

Configuration error detection is available in all Cyclone IV devices including
Cyclone IV GX devices, Cyclone IV E devices with 1.0-V core voltage, and
Cyclone IV E devices with 1.2-V core voltage.
Configuration error detection determines if the configuration data received through
an external memory device is corrupted during configuration. To validate the
configuration data, the Quartus
value for each configuration data frame and stores the frame-based CRC value in the
configuration data as part of the configuration bit stream.
Confirm the accuracy of the configuration data stored in an FPGA device
Alert the system to an occurrence of a configuration error
