(Xilinx Answer 33594) LogiCORE IP Tri-Mode Ethernet MAC - Frequently asked questions (FAQ)
- ISE 11.2 software support
- Virtex-6 support
- Spartan-6 support
- 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 Tri-Mode Ethernet MAC does not yet support these device 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 is not currently supported when targeting Spartan-6.
