The eye diagram result will be generated with the above settings. The eye diagram resulting from the time domain simulation is quite open and the 4-level signal can be clearly seen. Step 4: Generate response spectrum (optional) Circuit spectral response can be simulated by running a DC analysi...

注意在同一个设计中要使用同一个小写字母表示低电平有效; (7) 对于复位信号使用rst 作为信号名,如果复位信号是低电平有效,建议使用rst_n; (8) 当描述多比特总线时,使用一致的定义顺序,对于verilog建议采用bus_signalx:0的表示; (9) 尽量遵循业界已经习惯的一些约定。如*_r 表示寄存器输出,*_a 表示异步信号,...
