Using CLBs to perform clock de … WebTX clock skew: OPTIONAL The GMII-to-RGMII IP core has an option to add 2ns of skew to the TX clock. This option can be accessed in the Vivado GUI through the option “Skew added by PHY” (see below image). When this option is ticked, the core will output the TX clock without skew. When unticked, the core will output the TX clock with 2ns of skew.
