Question

We have used architectures that are structural and behavioral. Which of these is the easiest? Which is harder?

Answer 1

For modeling a hardware, one can write code in different ways, independent on the HDL you are using (i.e., either VHDL or Verilog). For Behavioral modeling the codes defines its functionality: it's like writing the algorithm that solves your problem. On the other hand the structural code, the different parts are connected together to get the final design.

For behavioral modeling , we just need to know the functionality of the block , So its simple. But for structural, one need to know with what component it is made of, so its hard as one need to know in depth.
