Behavior level description and RTL level description

Behavior level description focuses more on algorithms , Generally, the realization and integrability of the circuit are not considered , Only define the input-output relationship , The behavior of hardware circuits is usually described by process statements （ Final function of the circuit ）.

RTL Level is a register level description method to describe the data flow of a circuit , Its purpose is to integrate ,RTL Level does not care about the register itself and the implementation of combinatorial logic .
