B 用$setuphold可以检查setup和hold time C setup time不可以是负数 D hold time表示时钟有效沿到来之前多久,数据data就需要保持稳定的时间 解析: 首先A选项说保持时间可以是负数,这是不对的,我们一定要注意区别“保持时间”和“保持时间余量”,保持时间不能为负数,在理想情况下为0;而保持时间余量是可以为负数,...
The DFF was modeled in MATLAB Simulink software and calibrated by adjusting timing parameters. The CDR system was simulated in Simulink for three different cases: 1) equal setup and hold times, 2) setup time greater than the hold time, and 3) hold time greater than the setup time. The ...
