The Post CRC INIT Flag property (POST_CRC_INIT_FLAG) determines whether the INIT_B pin is enabled as an output for the SEU (Single Event Upset) error signal. This feature is only supported in 7 series FPGAs. For more information refer to the 7 Series FPGAs Configuration User Guide (UG470).
Tip: Alternatively, AMD recommends use of the
AMD Soft Error Mitigation (SEM) IP for all architectures.
This IP automates the implementation of single event upset (SEU) detection and
correction. For additional information, refer to the
Soft Error Mitigation Controller LogiCORE IP Product
Guide (PG036).
The error condition is always available from the FRAME_ECC site. However, when the POST_CRC_INIT_FLAG is ENABLED, which is the default, the INIT_B pin also flags the CRC error condition when it occurs.
This property is only applicable when POST_CRC is set to ENABLE.
