# Altera Quartus. Technology Map Viewer looks different from expected

Recently, I've installed Altera Quartus 15.1 and now follow the "getting started" instructions, you can read it here. At the step: to see the resulting circuit go to Tools →Netlist Viewers →Technology Map Viewer (post-mapping). After going there I get the following scheme:

Instead of much more demonstrative diagram from the tutorial:

Here is the code:

// file lab1.v
module lab1(SW,LEDG);
input [1:0]SW;
output [1:0]LEDG;
// input SW*, output LEDG*

endmodule

input a, b;
output cout, s;

assign {cout,s} = a+b;

endmodule


There are too much groupings and no view of underlying gates. I can't figure out how to adjust the view so it will be similar to what I see in the tutorial. Any suggestions?

Firstly, if you go to the "Equation" tab (in the bottom pane of the window), it shows you the equation for how the output relates to the input. In the equation view & means AND, # means OR, \$ means XOR, + means addition, and SUM()/CARRY() indicate the sum and carry of an adder block.
