Keywords: achieve timing closure  functional mode  transceiver design 

[Summary of tips] Transceiver channels configured in Basic (PMA Direct) functional mode only use the physical medium attachment (PMA) blocks of the transceiver channels. The physical coding sub-layer (PCS) blocks of all channels are bypassed.The interface between the transceivers and the FPGA core introduces significant delay on the clocks that ......
