IP Soft Error Mitigation Spartan-6 Error Injection limitation


SEM IP for Spartan-6 does not support injecting error to ECC word using Physical Frame Addressing.



A PFA-based error injection to the frames ECC word (WRD=65=x41) will inject an error in the wrong ECC word. 

If injecting an error into the ECC word using the PFA injection command, this may inject an error into the wrong ECC word.

This issue does not impact PFA injections into non-ECC words. 

The Workaround is to use LFA-based error injection when injecting into an ECC word.
