Recap - Loop Patterns

Part of the Fundamentals section of Coddy's Verilog journey — lesson 63 of 90.

Challenge

Complete the missing parts in each loop to produce the expected output.

What to do:

Use a for loop to print numbers 0 to 3
Use a while loop to print numbers 0 to 2
Use a repeat loop to print "Hello" 3 times

Try it yourself

module loop_patterns;
  integer i;
  
  initial begin
    $display("For Loop:");
    // TODO: Add for loop (i=0 to 3)
    
    
    $display("While Loop:");
    i = 0;
    // TODO: Add while loop (i=0 to 2)
    
    
    $display("Repeat Loop:");
    // TODO: Add repeat loop (print "Hello" 3 times)
    
    
    $finish;
  end
endmodule
