I didn't look at your design files, but I'll tell you what you should have.

The TX-to-RX path is serial, so whatever you send in parallel at the transmitter can be misaligned by any number of bits when received at the receiver. The receivers have word-alignment and bit-slipping controls. You need to first use those to align the receiver to your transmitted 8-bit/16-bit/32-bit data, and only then will your transmit data and receive data match. For example, you could send the static pattern ABCDh, and bit-slip at the receiver until you start receiving ABCDh, and then you would switch the transmitter to your counter.

Cheers,

Dave
