Solution

New Features 

- ISE 11.2 software support 

- Spartan-6 support 

- Virtex-6 support 

Resolved Issues 

- None 

Known Issues 

- Virtex-6 and Spartan-6 solutions are pending hardware validation. 

-Software Support for the Virtex-6 Lower Power parts was added in this release, but the 1000BASE-X PCS/PMA or SGMII Core does not yet support these devices and cannot be generated from CORE Generator targeting Virtex-6 Lower Power. Pending further testing, support for Virtex-6 Lower Power parts is planned for 11.3. To work around this issue, you can set your project to target an equivalent Virtex-6 LXT device, which will allow you to generate the IP. 

- Timing simulation not currently supported when targeting Spartan-6. 

- The TBI interface is currently not supported for Spartan-6 and will fail during BitGen.
