What is circuit design

What is circuit design?

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

Circuit design techniques

  • Schematic component creation for circuit design

    SCHEMATIC COMPONENT CREATION

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

  • Multi-schematic sheets

    MULTI-SHEET SCHEMATICS

    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 simulations

    SPICE SIMULATION

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