8 years agoHi sstrell,
I fixed this problem. It is not because of timing requirement, it is because I use the same clock input(CLK, shown in my code before) for this two ADCs. Actually these two ADCs can not work at the exactly same time. so they can not share the same clock. I will set DOUT as a basic clock to decrease that warning! DOUT is a combined pin, if there is no new data from ADC, DOUT acts as ready signal. Once there are new datas from ADC, DOUT trigger my board to send in SCLK and read data out. Thank you very much for your advise. Yours Yonghang Tian
