Figure 11–3. Error Detection Block Diagram
The user logic is affected by the soft error failure, thus reading out the 32-bit CRC
signature through the regout should not be relied upon to detect a soft error. You
should rely on the CRC_ERROR output signal itself, because this CRC_ERROR output
signal cannot be affected by a soft error.
To enable the <device>_crcblock WYSIWYG atom, you must name the atom for
each Cyclone III device family accordingly.
