What is circuit design?

Circuit design is the first step for every electronics design project. This requires the creation of a schematic diagram which defines how electronic components are logically connected on a printed circuit board (PCB). When the circuit design is complete, engineers can perform SPICE simulations or translate their schematic into PCB design software.

Circuit design techniques


    The creation of accurate electrical component symbols forms the foundation for a successful circuit design. Symbols provide all the parametric data needed to run accurate simulations, order manufacturable parts and provide connectivity on electronic circuits.


    Multi-sheet schematics help to manage and organise the complexity of advanced circuit designs. Multiple circuit designs can be hierarchically linked together with symbols to improve circuit readability and structure.


    SPICE simulation allows you to simulate and analyse the behaviour of a circuit design. Performing operating point, AC/DC sweep or transient analysis simulations identifies circuit performance issues without requiring a PCB prototype.
