Question
Q.2. What is behavioural model?
Answer
A behavioural model describes a circuit's functionality through an algorithmic description of its input-output relationship (using process statements and sequential code), rather than describing its internal structural composition.
A behavioural model in VHDL describes the intended function or behavior of a digital circuit using an algorithmic, software-like description (typically within a process statement containing sequential statements such as if-else, case, and loop constructs) that specifies how outputs should respond to inputs over time, without describing how that function is actually realized in terms of interconnected lower-level components or gates - it focuses purely on what the circuit does, not how it is structurally built.
