They do not loop like a C program loops. They only expand replicated logic. Let’s look at an example of this. Note that the code below is written in both VHDL and Verilog, but the simulation results are the same for both languages....
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; begin reverse[0] = data[3];...
Here is a simple example that illustrates the usage of a for loop. modulemy_design;integeri;initialbegin// Note that ++ operator does not exist in Verilog !for(i=0;i<10;i=i+1)begin$display("Current loop#%0d ",i);endendendmodule Simulation Log ncsim> run Current loop#0 Current loop...
Hi, When I use the normal for loop in verilog with the loop variable declared as a wire I get the following error 'i' is an invalid type in Generate loop...
I'm a beginner for verilog design. I have a question. Is there any way that could express a case statement in for loop including default part? I tried the code below. /// (reg [2:0] ctrl) for(i=0 ; i<5; i=i\+1) begin case(ctrl) i : begin out <= i; end endcase end...
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
I have been attempting to convert some code I have written from VHDL to Verilog without much success. My main stumbling block is the for loops in my VHDL code. My FOR loops have a much larger index, I am using 0 to 1 for simplicity. Simplified VHDL example: PROCESS(CLK) BEGIN IF...

I'm trying to understand why we use generate in verilog along with a for loop. Using a generate and for loop together: reg [3:0] temp; genvar i; generate for (i = 0; i < 3 ; i = i + 1) begin: always @(posedge sysclk) begin temp[i] <= 1'b0; end end endgenerate ...
