CMOS电路中的逻辑门有非门、与门、与非门、或非门、或门、异或门、异或非门,施密特触发门、缓冲器、驱动器等与非门则是当输入端中有1个或1个以上是低电平时,输出为高电平;只有所有输入是高电平时,输出...与非门(英语:NAND gate)是数字电路的一种基本逻辑电路。若当输入均为高电平(1),则输出为低电平(0);...

// Module code here endmodule Verilog 中的信号通常分为输入(input)、输出(output)和双向(inout)。输入是从外部传入模块的信号,输出是从模块传出的信号。 双向可作为输入或输出,通常用于双向信号,如总线。 1. 模块的结构 举例1:二选一数据选择器的Verilog描述。
This three-input NAND gate doesn't work. Fix the bug(s). You must use the provided 5-input AND gate: module andgate ( output out, input a, input b, input c, input d, input e ); 白话:修改三输入与非门的bug,并给一个5输入与门的子模块。
