Hi @MAOJUN ,. If I am not wrong it is 2*1 mux .So attached is code for the MUX 2*1 in vhdl. Thanks And Regards, Manish Nagpal A Tiny VHDL Guide 1.2.1 RTL VHDL RTL (\Register Transfer Level") code can be directly synthesized into hardware, in terms of gates, registers etc. 1.2.2 Behavioral VHDL Behavioral VHDL is used for simulation only. In addition to what can be described as RTL code, it can use much more complex constructions, e.g. le access. A 2-to-1 multiplexer consists of two inputs, one select input and one output. Depends on the select signal, the output is connected to either of the inputs. Since there are two input signals only two ways are possible to connect the inputs to the outputs, so one select is needed to do these operations.
