Many circuitry configurations are used in the construction of a new building. All of which need to be designed to a high, functioning standard. The design of these circuit boards can be done using several different modelling techniques, including bread board modelling and circuit modelling.

A Circuit model is essentially a mock up of a potential design. A functional diagram usually created in a CAD program. It is used to make sure the requirements that the potential circuit will meet the requirements of the brief and the specification upon completion.

Bread board modelling is a common form of modelling that uses a physical prototype board, also known as a bread board. This is a board covered with small sockets into which components can be plugged.

Both forms of modelling can be used to test a design. Once a design has been evaluated, this can be used to create the final product.
