You can use the GCLK_DESKEW property to disable calibrated deskew for a clock net. For devices that support calibrated deskew, the initial delay taps for a clock network are calibrated at device startup to further minimize clock skew when calibrated deskew is enabled for a clock net. For more information on default calibrated deskew settings for different Versal devices, see the Versal Adaptive SoC Clocking Resources Architecture Manual (AM003). For some clocking topologies, it is more important to minimize insertion delay, and clock network deskew is less important for timing closure. In these cases, you can implement a clock network without additional delays to balance clock skew by setting the GCLK_DESKEW property on a clock net to OFF. This also disables calibrated deskew for the clock net. You must set the GCLK_DESKEW property on the net segment directly driven by the clock buffer. Following is an example:
set_property GCLK_DESKEW OFF [get_nets -of [get_pins clkgen/BUFG_clkout2_inst/O]]
