stream operator(流操作符)是你的选择。示例写法如下 localparam HEX = 4; localparam LEN = 4; typedef logic [HEX-1:0] Hex; module Reverse ( input clock , input wen , input Hex [LEN-1:0] A , output Hex [LEN*4-1:0] C ); Hex [LEN*4
5.2.3 流(也叫打包/解包)运算符(<<,>>) Streaming (aka pack and unpack) operators (<<, >>) 流运算符以位串流(bit serial stream)的方式从向量中推出,或者向其推入一组bit。流运算符可用于将数据打包(pack)至一个向量中,或从一个向量中解包(unpack)数据。 {<<M{N}}:从N中按顺序流出大小为M的...
private MemoryStream memStrm; /// /// 功能简述: 构造函数 /// public CSuperString() { memStrm = new MemoryStream();//初始化流 } /// /// 功能简述: 构造函数 /// /// 默认长度(以字节为单位) public CSuperString(int DefaultLength) { memStrm = new MemoryStream(DefaultLength);//初始...

list, whereas C uses { }. Early versions of the SystemVerilog draft standard used simple{ } braces to delimit value lists, like C. The final version of the IEEE SystemVerilog changed the delimiter to ’{ } to distinguish the list of values from Verilog’s { } concatenation operator. ...
