SystemVerilog -- 3.3 SystemVerilog for loop SystemVerilog for loop SystemVerilog中的循环多次重复一组给定的语句,直到不满足给定的表达式。与所有其他过程块一样,循环中需要多个语句被for和for begin end关键字括起来。 Syntax For循环使用三步方法控制其语句的执行: 初始化影响循环运行次数的变量 在执行循环之前,...
SystemVerilog -- 3.2 SystemVerilog foreach loop SystemVerilog foreach loop SystemVerilog数组是允许在单个变量中存储多个值的数据结构。循环仅用于遍历此类数组,并且是执行此操作的最简单和最简单的方法。foreach Syntax 循环从0开始循环访问每个索引。如果循环中有多个语句,则必须像所有其他过程块一样用foreach和for...
module for_loop3( input logic [3:0] din, output logic [1:0] dout ); always_comb begin dout = 0; for (int i=0; i<4; i++) begin if (din[i] == 1'b1) begin dout = i; end end end endmodule 实际上例3的for循环实现了一个优先级电路,其展开后为如下所示的代码。 always_comb...
Loop循环中的foreach,是专门针对数组轮询时候用的。对二维数组遍历,如下代码: 1 int data[3][4]; 2 initial 3 foreach(data[1]) begin 4 foreach(data[i][j]) begin 5 </**/> 6 end 7 </**/> 8 end 9 end 1. 2. 3. 4. 5. 6. 7. 8. 9. 在两个for循环中,可以在里面直接定义inde...
for循环的实质:Verilog中的for循环起电路复制的作用 for循环一般写在testbench中做测试用,而不是写在module中。 Verilog模块内部也是能写函数的! 【Verilog Function函数语法说明】 function [3:0]FUCTION_NAME; input [SIZE-1:0] input_data; input [SIZE-1:0] other_input; ...
A for loop in SystemVerilog repeats a given set of statements multiple times until the given expression is not satisfied. Like all other procedural blocks, the for loop requires multiple statements within it to be enclosed by begin and end keywords. Syn

A for loop is the most widely used loop in software, but it is primarily used to replicate hardware logic in Verilog. The idea behind a for loop is to iterate a set of statements given within the loop as long as the given condition is true. This is very
