Swap / Buffer Circuit

Swap / Buffer circuit can be implemented by using a simple 2X1 Multiplexer.

Swap/Buffer circuit Verilog Code

module swap_buffer(a,b,s,out1,out2);

input a,b,s;

output out1,out2;

mux2x1 m1(.in1(a),.in2(b),.sel(s),.y(out1));

mux2x1 m2(.in1(b),.in2(a),.sel(s),.y(out2));

endmodule
