ERROR:ConstraintSystem:59 - Constraint <NET "phy_4x_ser_clk/UCLK_DV4" TNM_NET =
"UCLK_DV4";> [xiltest_srio_v5_6_top.ucf(94)]: NET "phy_4x_ser_clk/UCLK_DV4"
not found. Please verify that:
1. The specified design element actually exists in the original design.
2. The specified object is spelled correctly in the constraint source file.

Solution

This is a known issue. To work around this issue, edit the UCF file as below:

From:

NET "phy_4x_ser_clk/UCLK" TNM_NET = "UCLK";
NET "phy_4x_ser_clk/UCLK_DV4" TNM_NET = "UCLK_DV4";

To:

NET "*UCLK" TNM_NET = "UCLK";
NET "*UCLK_DV4" TNM_NET = "UCLK_DV4";
