肯定是可以的直接输出到管脚的,一般建议输出到pclk,如果是这个时钟是一对差分对,建议输出到pclkT。
测不到信号很可能是你代码的问题。可以把你的代码贴出来看看。
好的,我再找一下原因
这样是可以的,没有问题
iDD4 u_iDD4(.alignwd(1'b0), .clk(DCK), .clk_s(DCK), .init(1'b1), .reset(~reset_n), .rx_ready( ), .sclk(byte_clk), .datain({D3, D2, D1, D0}), .q(data))/* synthesis syn_noprune=1 */; 是差分时钟对,我是直接使用这个IP,然后byte_clk直接输出到pclkT的引脚的,这样是否可行呢?
