Solution

General Information

The ISE 14.7 design tool release contains the v1.11 core.
For 7 series Integrated Block for PCI Express v2.2 core release notes, see (Xilinx Answer 54643).
For 7 series FPGAs GTX/GTH transceivers known issues and answer record list, see (Xilinx Answer 37179).

New Features

ISE 14.7 design tool support.

Supported Devices

Virtex-7, Kintex-7, Artix-7, Zynq-7000
7 series Integrated Block does not support targeting SSIT devices with the ISE tool flow. Customers that want to target SSIT devices (1500T and 2000T) must use the Vivado development environment.
For specific device support within each family, see the product guide.

Note: For the previous versions "New Features" and "Supported Devices", see the readme.txt or version information file available with the generated core.
