Note that is just a shorter version to the following loop : `foreach` `for` for(inti =0; i <$size(array); i++)begin// Statements inside the for loopend Example #2: Multidimensional Arrays module tb;intmd_array [
foreach, return, break, continue等流控制符。 Verilog Basics 主要介绍 Verilog 的基本语法。这里只记录几个平时不常用的语句: For Loop 和 Repeat ,用于重复执行代码/生成模块。用法: //for loopintegeri;for(i=0;i<16;iy)temp=x;elsetemp=y;
SystemVerilog foreach specifies iteration over the elements of an array. the loop variable is considered based on elements of an array and the number of loop variables must match the dimensions of an array. foreach loop syntax foreach(<variable>[<iterator>]]) begin //statement - 1 ... /...

3.5 foreach循环 语法结构: systemverilog foreach (array[index]) begin // 循环体 end 解释: array[index]:遍历数组的每个元素,index是自动生成的索引变量。 示例代码: systemverilog module foreach_loop_example; initial begin int array[5] = '{0, 1, 2, 3, 4}; foreach (array[i]) begin...
for(int i=10,i>=0,i--) $display("loop2 i is %d\n",i); #1; end 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. System Verilog允许初始声明或赋值语句可以是一个或者多个用逗号分隔的语句。 例子: for(int i=0,j=0;ij<=50;i++,j++) ...
foreach (array [index]) begin $display ("array[%0d] = 0x%0d", index, array[index]); end 其他三个都与C中的逻辑一致,不再赘述。 中断循环 在C中我们用continue和break来对循环进行中断,在systemverilog中我们还是使用它们。 break结束循环,continue结束本次循环。
{6,0,2,3,4,5} 在队列前面插入6 j=q.pop_back; //{6,0,2,3,4} 从队列末尾弹出5,所以j=5 q.push_back(8); //{6,0,2,3,4,8} 从队列末尾插入8 j=q.pop_front; //{0,2,3,4,8} 从队列后面弹出6,所以j=6 foreach(q[i]) $display(q[i]); //打印 q.delete(); //{} ...
也是从C语言中引进来的,包括do-while循环,break 和 continue。新的foreach操作符用在数组变量中。而且增强了for循环的功能,下面的做法是正确的, for (int i = 15, logic j = 0 ; i > 0 ; i--, j = ~j) 标签 在Verilog中, 你可以这样标识begin 和 fork语句: begin : a_label ...
— enhanced loop statements plus the foreach statement — C like jump statements: return, break, continue — final blocks that executes at the end of simulation (inverse of initial) — extended event control and sequence events — Enhanced process control ...
