More logic gates (Gates)

Problem Statement

Ok, let's try building several logic gates at the same time. Build a combinational circuit with two inputs, a and b.

There are 7 outputs, each with a logic gate driving it:

• out_and: a and b
• out_or: a or b
• out_xor: a xor b
• out_nand: a nand b
• out_nor: a nor b
• out_xnor: a xnor b
• out_anotb: a and-not b

Expected solution length: Around 7 lines.

module top_module( 
    input a, b,
    output out_and,
    output out_or,
    output out_xor,
    output out_nand,
    output out_nor,
    output out_xnor,
    output out_anotb
);
	assign out_and = a&b;
    assign out_or = a|b;
    assign out_xor = a^b;
    assign out_nand = ~(a&b);
    assign out_nor = ~(a|b);
    assign out_xnor = a^~b;
    assign out_anotb = a&(~b);
endmodule
