    Subject: [oc] Physical design rules error during mapping with Xilinx8.1i
    Top
    Hi

    i am having problems with trying to generate a bitfile for my design.
    I am using Xilinx 8.1i and it is reporting the following errors during
    mapping and place and route.

    ERROR: PhysDesignrules:760 - Incompatible programming for IO Standard.
    IO Standard LVDS_25 of comp IO_x_x_x_X_x_x_x/iobuf_dqs/
    IO does not allow both input and output programming on the same comp.

    Does anyone know anything about this error?
