11.5 Design Tools Information

Version 11.5 includes important updates and supports production devices for the Virtex-6 and Spartan-6 device families.

However, several work-arounds might be required for Virtex-6 and some Spartan-6 FPGA customers using ISE 11.5 design tools.

Please review (Xilinx Answer 32147) before you upgrade to ISE 11.5 design tools.

These work-arounds are addressed in ISE 12.1 design tools, released in May 2010.

12.1 Design Tools Information

At this time, ML605 Evaluation Kits are not shipped with ISE Design Suite version 12.1.

The reference designs (shipped with the kits and available on-line) are only supported in version 11.4 of the tools.
