Never used these draw the waveform type of simulators. But I'm assuming you probably have to add the signals into the waveform window and draw the signals.
You would be better off learning how to write a testbench and running this in Modelsim AE. That at least gives you marketable skill, unlike learning that Quarus vector drawing tool.
Mostly agree with ads-ee. Vector waveform editor has been used with the old Quartus built-in simulator, available till V9 or so. Later Altera provided a converter in the University Program that drives Modelsim from the waveform file.
I still find the simulator appropriate for small simulation problems.
can you tell me how I have to do to generate vector waveform
Pretty much they way I thought you would have to enter them, All the waveform creation tools seem to work the same way. I've used Timing Designer and a couple of other similar tools in the past.

A testbench like this would check all valid input combinations (invalid ones like U, X, and Z are not checked).
// brute force approach`timescale1ns/1psmodule and_brute_force_tb;reg a,b;wire and_out;initialbegin
a =0;
b =0;#10;
a =1;
b =0;#10;
a =0;
b =1;#10;
a =1;
b =1;#10;end
and_gate uut (
.a (cnt[0]),
.b (cnt[1]),
.y (and_out));endmodule
. Do you have quartus? Do you use? I just wanted to know behavior of signals. I want to make block schematic diagram, and time diagram. Is it possible with quartus? Suggest me, what I do
I've used Quartus in the past but haven't used it for about 3-4 years.
To generate a schematic of the circuit you can just have Quartus produce a RTL schematic view (or something like that) or a Technology view (not sure if that is what they call that either). To get a timing diagram try one of the testbenches and run a simulation with all the signals displayed in the waveform window.
Not sure what your objective is with doing all this...seems rather pointless to me. An AND gate is an extremely simple thing and the truth table should be enough to understand it.
