半加器要实现的功能就是没有进位输入、但有进位输出的两个1bit数的加法(电路行为),即 {C,S} = A + B; 所以用行为级描述方式来描述电路,是这样的: module half_adder( input A,B, output S,C ); assign {C,S} = A + B; endmodule 这是用vivado生成的电路: 就是个半加器,具体怎么实现的不知道...
Create a half adder. A half adder adds two bits (with no carry-in) and produces a sum and carry-out. Expected solution length: Around 2 lines. Answer1 module top_module( input a, b, output cout, sum ); assign sum = a ^ b; assign cout = a & b; endmodule ...

这段代码是用Verilog HDL(硬件描述语言)编写的,用于描述一个数字电路模块。Verilog常用于模拟和描述电子系统,尤其是数字电路和系统。以下是对代码的逐行解释: 时序和模块声明 timescale 1ns/1nsmodule test ; timescale 1ns/1ns:定义时间单位和时间精度都为1纳秒。
Verilog is one of the Hardware Description Language (HDL) used to model the electronics systems at the following abstraction levels:Register Transfer Level (RTL) - An abstraction level, where the circuits are modelled as the flow of data between registers. This is achieved through always blocks ...
