Question

explain how Modular Design is beneficial and how do the component statement and pirt maps work?

Answer 1

Benefits of Modular Designing:

• Modular designing is defined as breaking the problems into subparts where each part is independent of one another.
• Modular designing makes the process easy as it divides the problem into subpart and each individual can focus on the single part.
• Testing of software becomes easy and we can detect the bugs easily.
• If some changes are required in the future, so there will be a change in only a single module rather than a complete program.
• Each module is configured independently so modules are reusable and can be used in other projects too.

Component Statement and Port Map:

• Component statements are the statements that are written inside the component module. The component module is a kind of module which is a reusable module of VHDL and can also be declared inside another logic circuit. Port Map is the process that maps the input and output of components that are used in the component module.
• Thus the port map is interconnection between the component modules.
• Port map can map the components via positional Port Map or Nominal Port Map.
