IBUFDS_GTE2_driven_by_IBUF

[DRC REQP-1619] IBUFDS_GTE2_driven_by_IBUF: IBUFDS_GTE2 u_ad9166/da_jesd204b_inst/i_jesd204_0_support_block/i_shared_clocks/ibufds_refclk0 pins I and IB should be driven by IBUFs. 错误。大概意思是需要加IBUF

IBUF IBUF_instI (
.O(refclk_pad_p_i), // Buffer output
.I(refclk_pad_p) // Buffer input (connect directly to top-level port)
);
IBUF IBUF_instIB (
.O(refclk_pad_n_ib), // Buffer output
.I(refclk_pad_n) // Buffer input (connect directly to top-level port)
);
