Design a 16-bit multiplexer in Verilog.
Implement a synthesizable 2:1 multiplexer with 16-bit inputs a and b, a one-bit select signal sel, and a 16-bit output y. When sel is 0, y must equal a; when sel is 1, y must equal b. Provide the Verilog module and briefly explain the behavior. The Python function below models the same combinational logic for automated checks.
a and b are 16-bit unsigned values from 0 through 65535sel is either 0 or 1def mux16(a, b, sel):
