这里以简单的3-8译码器和8-3编码器为例: moduledecoder3_8(a,out);input[2:0]a;output[7:0]out;assignout=1'b1<<a;/*把最低位的1左移in位(根据in口输入的值)并赋予out*/endmodule 8-3编码器程序: 1)利用for循环 View Code 2)利用?:三目运算符 1moduleencoder8_3(a,b,c,d,e,f,g,h,ou...
2. 与Systemverilog新支持的for循环关键词break结合,就可以比较方便地写出带参数的有优先级逻辑。(请避免在工作中使用 `define WIDTH 8 logic [$clog2(WIDTH)-1:0] dout; always_comb begin dout = WIDTH-1; for (int i = 0; i<WIDTH; i++) begin if (din[i] == 1'b1) begin dout = i; br...

Decoder模块,命名为DEC。 5. 模块之间的接口信号的命名。 所有变量命名分为两个部分,第一部分表明数据方向,其中数据发出方在前,数据接收方在后,第二部分为数据名称。 两部分之间用下划线隔离开。 第一部分全部大写,第二部分所有具有明确意义的英文名全部拼写或缩写的第一个字母大写,其余部分小写。 举例:CPUMMU_Wr...
