以下是一个简单的Verilog示例,展示了如何使用for循环嵌套来初始化一个二维数组: verilog module nested_for_loop_example(); reg [7:0] arr[3:0][3:0]; // 定义一个4x4的8位寄存器数组 integer i, j; initial begin // 使用for循环嵌套初始化二维数组 for (i = 0; i < 4; i = i + 1) ...
module nested_for_loop(); integer i, j; initial begin for (i = 0; i < 3; i = i + 1) begin for (j = 0; j < 3; j = j + 1) begin $display("i = %0d, j = %0d", i, j); end end end endmodule 这个例子展示了如何使用嵌套的for循环来遍历二维空间(或矩阵)的索引。
The basic solution working without "advanced" Verilog syntax, that's possibly missing from a "Verilog for beginners" tutorial, is using nested loops. Although VHDL to Verilog translation by trial-and-error method will work somehow, it's possibly less frustrating with a profound Verilog...

Generate loops can also nest. Only a singlegenerate/endgenerateis needed (or none, since it’s optional) to encompass the nested generate loops. Remember each generate loop creates a new scope. Therefore the hierarchical reference to the inner loop needs to include the label of the outer loop...
