`define CLOCK_PERIOD 10 //定义一个时钟周期为10个时间单位 always @(posedge clk) begin if (counter == `CLOCK_PERIOD) begin //在这里使用了`CLOCK_PERIOD宏,会被替换为10 counter <= 0; end else begin counter <= counter + 1; end end ``` 2.条件编译:通过`define`可以启用或禁用某些代码块,...
`define CLOCK_PERIOD 10。 在代码中,我们可以使用`CLOCK_PERIOD来代替实际的时钟周期数值。这样,如果以后需要修改时钟周期,只需要修改宏定义的数值,而不需要在整个代码中逐个修改。 除了数值,`define指令也可以用于定义字符串,例如: `define COMPANY_NAME "ABC Corporation" 在代码中使用`COMPANY_NAME时,它会被替换...
`define CLOCK_PERIOD 10 然后,在代码中可以使用`CLOCK_PERIOD代替具体的时钟周期值。 2.定义宽度参数 `define可以用于定义宽度参数,方便在代码中统一调整宽度。这在设计中常常需要使用到。 例如,我们可以使用`define定义一个数据宽度: `defineDATA_WIDTH 16 然后,在代码中可以使用`DATA_WIDTH代替具体的数据宽度值。
The delay between CLKA and CLKB is modeled as clock latency (both by TimeQuest and Classic). So, all you need to do is: create_clock -period 10 CLKA create_generated_clock -divide 2 -source CLKA CLKB TimeQuest will then do everything right. If you want to then ...
