The SEM IP can be configured to detect or detect and correct soft errors. Therefore, consideration must be given to the system-level actions, if any, that must be taken in reaction to soft errors. If no action is taken when a soft error is detected in a design, the benefits of having the SEM IP in the design should be assessed and understood. While this is a valid use case, the effects of soft errors on the design should be known and this mitigation approach should be well understood to ensure it meets the soft error mitigation goals.
RECOMMENDED: When using the SEM IP in a design, it is strongly recommended to log the output of the Monitor interface.
This Figure shows an example of a decision tree that iterates what a system could do when a soft error occurs. By understanding the possibilities and the system-level considerations, a decision can be made to determine whether or not to use the SEM IP in a design.
Note: This diagram is provided as an example and it does not list all the possible considerations.
