Soft Error Mitigation (SEM) IP – UltraScale+ Architecture SSI devices do not assert all of the status_* signals during halt condition (HLT)


When a halt (HLT) condition occurs in UltraScale+ family SSI devices, the Soft Error Mitigation (SEM) IP does not assert all of the status_* signals HIGH.

The following signals remain LOW:

  • status_diagnostic_scan
  • status_detect_only


The issue is that two signals are not driven high as specified.

As a work-around, monitoring the other five status signals for simultaneous assertion will indicate a HLT condition, and it can be reliably detected.

This will be addressed in the next release.
