Spartan-6 FPGA SP605 Evaluation Kit dimensions have changed in order to make the SP605 CE compliant.
This change in dimensions was needed to implement extra EMI filter circuitry around each regulator on the kit.
The Spartan-6 FPGA SP605CE compliant kits are 0.5 inches longer than previous board versions. The height ofthe kit did not change. The back end mounting holes of the CE compliant kit were moved by 0.5 inches. You can identify the CE-complaint SP605 through the number marked on the sticker on the underside of the board. For CE compliant SP605, this will begin with "0431767".
The physical sizes can be found in the respective BRDfiles and Gerbers as shown below.
