Vivado versions prior to 2016.1 are configured with a stronger drive than expected for HSTL_12, DIFF_HSUL_12_DCI and HSUL_12_DCI Solution In Vivado versions prior to 2016.1, HSUL drivers default to an output impedance setting of RDRV_40_40. In Version 2016.1 and beyond the settings will ...
该错误提示约束属性中约定了DIFF_TERM_ADV,但是DIFF_HSTL_I_12电平标准不支持。具体的原因笔者不太清楚,但是大概是和电平标准还有BUFG相关。在我的代码中,引入了差分时钟信号clk_p、clk_n,但是需要使用单端信号,因此使用IBUFDS对信号进行了转换。代码如下: IBUF
