Small Description about Structural Modeling Style in VHDL.
Structural Modeling Style -
Structural Modeling Style shows the Graphical Representation of modules/ instances / components with their Interconnection.
In Structural Modeling Style We defines that how our Components / Registers / Modules are Connected to each other using Nets/ Wires.
- Structural Modeling Style works on Concurrent Executions.
Basic Structure Design Outline -
- Component Declaration.
- Signal Declaration.
- Component Instantiation.
- Declare a list of Components being used.
- Declare signals which define the nets that interconnect components.
- Label multiple instances of the same component so that each instance is uniquely defined.
*
- COMPONENTS & PORT MAP Statements are used to implement structural modeling.
- The Component instantiation statements ar concurrent statements.
