Small Description about Data Flow Modelling Style in VHDL.

Data flow modeling style—

Data flow modeling style shows how the data flow from input to output threw the registers / components.

Data Flow Modeling Style works on Concurrent Executions.

Concurrent Statements in VHDL-

• Concurrent Signal Assignment (<=).
• With Select Assignment.
• When Else Assignment.
• Generate Expressions.

Sample Programs of Data Flow Modelling Style-
