`define clk_period 20 //定义时钟宏clk_period 这相当于告诉综合软件,在程序中遇到的 `clk_period 时均等同于 20。定义宏语句的最后是没有分号 ; 的,如果不小心加了分号,那么这个分号则会被视为“macro_text”的一部分而参与替代工作。 宏定义被调用的格式是: `macro_name(formal_argu_list) 比如调用上面...
`define clk_period 20 always #(`clk_period/2)clk=~clk; 需要特别注意的是`define语句后⾯是 不加分号的!!不加分号的!!不加分号的!! 这是⼀个刚开始使⽤宏的新⼿很容易踩得坑 ⼆、ifdef 条件编译 宏不仅仅可以⽤来定义参数,还可以实现条件编译。 `ifdef 之后的宏 如果被定义过那么执⾏ifd...
