｀define 是宏定义，全局作用的，而且不受语意限制。你甚至可以定义半截的字符串出来。但是使用的时候才会做展开。举例而言，如果你定义一个宽度信息为：｀define RANGE 2:3 然后在使用的时候｀include这个文件，RANGE就可以解析了。wire [`RANGE] bus;parameter是模块内常量定义，仅限于常量。一般的工...
`include "constants.v" ``` 这里将文件constants.v的内容插入到当前文件中。 7.只读的参数: 使用`define定义的常量是只读的,无法在模块内部修改其值。 ```verilog `define WIDTH 8 module my_module(; reg [`WIDTH-1:0] data; initial begin $display("Width: %0d", `WIDTH); //错误的修改,会导致...
1、把所有宏定义放到一个宏定义文件(global_define.v); 2、在某个文件需要使用这些参数时,需要使用该指令--`include "global_define.v" 来将该宏定义文件调用; 3、在需要使用到具体的宏时,直接使用,但是要记得加 ` ,比如: ` H_SYNC 。

During the development of code that emits dynamic assemblies, it is recommended that you use an overload of the DefineDynamicAssembly method that specifies evidence and permissions, supply the evidence you want the dynamic assembly to have, and include SecurityPermissionFlag.SkipVerification in refused...
In Windows PowerShell version 3.0 and newer, modules load automatically if you run a cmdlet that is part of that module. This works if the module that contains the cmdlet is in a folder under the module load paths. By default, these folders include%systemdir%\WindowsPowerShell\v1...
