I have also tried modifying the constraints on the pin in the UCF file. But CE of FDCE are not used. UltraScale Architecture Clocking Resources www. My design fails to meet all constraints, and throws the following message: "WARNING:Route - CLK Net:dsp_clk_a_IBUFG may have excessive skew because 685 CLK pins and 1 NON_CLK pins failed to route using a CLK template. If clock gating is absolutely required, BUFGMUX and BUFGCE should be inferred or instantiated, and extra care should be taken to ensure that no glitches occur on the clock line that could affect design functionality. In addition, there is a local BUFCE_LEAF clock buffer for driving leaf clocks from horizontal distribution to various blocks in the device. But CE of FDCE are not used.
