Properly planning the device orientation on the board and assigning signals to specific pins can lead to dramatic improvements in overall system performance, power consumption, thermal performance, and design cycle times. Visualizing how the device interacts physically and logically with the printed circuit board (PCB) enables you to streamline the data flow through the device.
Failing to properly plan the I/O configuration can lead to decreased system performance and longer design closure times. Xilinx highly recommends that you consider I/O planning in conjunction with board planning.
