the functionality of the circuit is to AND the two inputs and put the result on the output port. To describe the operation of the circuit, VHDL adds an “architecture” section and relates it to circuit_1 defined by the entity statement. The...

Create a Mux in Verilog and VHDLA multiplexer (or Mux) is another word for a selector. It acts much like a railroad switch. This picture shows two possible source tracks that can be connected to a single destination track. The railroad switch controls via some external control which train ...
Hello , I am starter in VHDL . Is there any difference between two sources below? They are different i think. first source uses vector signal in the entity body. second source uses vector signal in the architecture body. is ther any difference? for example concurrent process or seque...

My question is the following: are all signals (in a diagram linked below) considered to be bit vectors? diagram =>http://s014.radikal.ru/i328/1505/06/472c30243696.png Here is the code that just does not want to compile: entitysum1_1isport(a3,a4:inbit; ...
Here is an example of HDL code: 1 entity Circuit_1 is 2 Port ( a : in STD_LOGIC; 3 b : in STD_LOGIC; 4 out1 : out STD_LOGIC); 5 end Circuit_1; --- 6 architecture Behavioral of Circuit_1 is 8 begin 9 out1 <= ( a and b ); 10 end Behavioral; The electrical behavior...
