- ISE 11.1 software support

- Virtex-6 support

- Spartan-6 support

- Virtex-5 TXT support

- Option to generate without Half Duplex logic for Full Duplex applications

- Option to generate with a Media Independent Interface (MII) for 10Mb/s and 100Mb/s only Ethernet speed support

- Option to generate for 1Gb/s only Ethernet speed support: this option replaces the 1-Gigabit Ethernet MAC LogiCORE.

- Example Design Verilog language updated to Verilog 2001 syntax, including port map definitions, use of generate statements and generic/attribute set syntax.

- Example Designs for the Virtex-4 family have been updated with new logic for the GMII and RGMII physical interfaces to improve input setup/hold timing margins. The new logic now uses DCMs.

- RGMII Example Design (using clock enables) updated to allow transmitter global clock sharing across multiple core instantiations.

Bug Fixes

(Xilinx Answer 30644) When using RGMII and Spartan-3 family devices, the example design has a missing period contraint.
