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 Tool Version | Vivado Tool Version |
| v12.0 | Not Supported | 2013.1* |
| v11.6 | ISE 14.5 | Not Supported |
| v11.5 | Not Supported |
2012.4 |
| v11.4 | ISE 14.2 | 2012.2 |
| v11.3 | ISE 14.1 | Not supported in Vivado Design Suite 2012.1 |
| v11.2 | ISE 13.3 | NA |
| v11.1 | ISE 13.1 | NA |
Note: For release notes and known issues for v12.0 and later of the core, see (Xilinx Answer 54252).
The following table provides known issues for the 10-Gigabit Ethernet MAC core, starting with v11.1, 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 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.
