A second Gray code counter style, the one described below, uses two sets of registers, one a binary counter and a second to capture a binary-to-Gray converted value. The intent of this Gray code counter style #2 is to utilize the binary carry structure, simplify the Gray-to-binary conve...
// code to be executed end ``` 在for循环中,初始化(initialization)块用于设置循环变量的初始值。条件(condition)是一个逻辑表达式,用于检查循环是否应该继续执行。增量(increment)用于指定每次迭代后循环变量的变化方式。 例如,在Verilog中使用for循环创建一个简单的计数器如下所示: ``` reg [3:0] counter; ...

来一个前面完成效果的 counter.v，代码太长了，放在后面附录。在 .v 文件里执行 Run Code，可以点右上角的小三角，可以右键菜单里运行，也可以快捷键 Ctrl + Alt + N。执行完成后在当前目录下会生成两个文件 run.vvp 和 run.vcd。右键 run.vcd 执行 Run Code。在弹出的 GTKWave 窗口中，展开 counter_tb...
