After the test completes, Altera recommends reconfiguring the device.
Stratix IV devices offer on-chip circuitry for automated checking of SEU detection.
Some applications that require the device to operate error-free in high-neutron flux
environments require periodic checks to ensure continued data integrity. The error
detection CRC feature ensures data reliability and is one of the best options for
mitigating SEU.
You can implement the error detection CRC feature with existing circuitry in
Stratix IV devices, eliminating the need for external logic. The CRC_ERROR pin reports a
soft error when the configuration CRAM data is corrupted. You must decide whether
to reconfigure the device or to ignore the error.
Depending on the type of error detection feature you choose, you must use different
error detection pins to monitor the data during user mode.

The WYSIWYG function performs optimization on the Verilog Quartus Mapping
(VQM) netlist within the Quartus II software.

Pin-Outs
Active-high signal indicates that the error detection circuit has detected errors in the
configuration CRAM bits. This pin is optional and is used when the error detection CRC
circuit is enabled. When the error detection CRC circuit is disabled, it is a user I/O pin.
To use the CRC_ERROR pin, you can either tie this pin to V
depending on the input voltage specification of the system receiving the signal, you can tie
this pin to a different pull-up voltage.
