Prototype Circuit

Electronic circuits can be modelled using a prototyping board (or breadboard).

This can be time consuming and uses real components, which can be damaged. Computerised simulation software can be used to test circuits without the need to physically build them. In addition, the computer simulation can be saved and edited.

Software can also be used to simulate control programmes for programmable interface controllers (PIC). Flowchart symbols can be placed or dragged on-screen. The action will be simulated to ensure that they operate as intended.


  • You can save and edit ideas, which make it easier and cheaper to modify your design as you go along.
  • Speeds up production process.
  • Doesn't require any physical components, so money isn't wasted on expensive parts
  • You can choose pre-drawn circuits or system blocks, which speeds up the process even further.


  • Staff need to be trained how to use the software, which also adds to costs.
  • The software itself can be expensive so initial costs are high. There are free software packages though.
  • It doesn't always accurately simulate 'real world' circuits or ideas, so may not be as effective as a prototyping board.
  • Requires a PC.


This is a reusable method because the connections can be inserted and removed without soldering.
