WebIn the case of FPGA outputs, you should generally try to drive those signals from a register output, as that ensures the signals are glitch free. If the output signals are going to logic clocked by the same clock as the FPGA, then you would setup a TimeQuest timing constraint indicating the timing.

WebJul 5, 2010 · I'm currently using a Xilinx dedicated-virtex5 primitive module for a clock multiplexing function called "BUFGMUX_CTRL". During synthesis I faced several problems with this module which gave some bad performance in terms of clock timing. This module is considered as a glitch-free 2:1 multiplexer, that's why I would like to use it. http://www.elecdude.com/2016/03/glitch-free-clock-gating-verilog-code.html
