![]() ![]() ![]() Shouldn’t we know the logic equation for the priority encoder? To describe the circuit using the logic equation, this modeling uses the keyword assign. You can read all about the dataflow modeling technique in Verilog over here. Hence, it is much easier to construct complex circuits using this level of abstraction since there is no need to know the actual physical layout. We need not bother about the gates that make up the circuit. In this modeling technique, we use logic equations to describe the flow of data from input to the output. So, our final code is: module priority_encoder_42(A0,A1,Y0,Y1,Y2,Y3) We use the gate (,) syntax to use the in-built gates in Verilog. From the above circuit, the signals from NOT and AND gates can be treated as intermediate signals. These are signals that are not the terminal ports. Now, we can declare the intermediate signals.
