Virtex-6 11.4 ISE - Virtex-6 FPGA designs must be re-run through implementation in ISE 11.5 or later software

Description

Virtex-6 FPGA routing models are changed in version 11.5 and later of the ISE Design Suite software, requiring Virtex-6 designs created in 11.4 ISE to be re-run.

Solution

Due to changes in the routing models of the Virtex-6 FPGA, all Virtex-6 designs must be re-run through implementation in a version of ISE Design Suite software later than 11.4. These changes have been implemented in ISE versions 11.5 and later.

To create a valid design, existing designs must be re-run through implementation (at minimum MAP and PAR) in 11.5 or later ISE Design Suite software.
