General Known Issues

This table correlates the core version to the first ISE or Vivado design tools release version in which it was included.

Core Version ISE Tools Version Vivado Tools Version
v5.5 ISE 14.4 2012.4
v5.4 ISE 14.2 2012.2
v5.3 ISE 14.1 2012.1
v5.2 ISE 13.4 NA
v5.1 ISE 13.1 NA

The following table provides known issues for the Tri-Mode Ethernet MAC core, starting with v5.1, initially released in ISE Design Suite 13.1.This is the first version to support 7 series devices and have an AXI interface. For earlier versions of the core using the legacy user interface, please refer to the IP Release Notes Guide for the release notes answer record by version.

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.
