Known and Resolved Issues

Table 2 provides a list of post-2015.1 MIG UltraScale RLDRAM3 IP patches that are recommended be installed if currently in production but are unable to upgrade the IP to 2016.1.

All other users are recommended to upgrade to 2016.1.

Table 3 provides the known and resolved issues for the UltraScale family RLDRAM3 IP.

Note: The "Version Found" column lists the version the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
