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.

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-sheet schematics help to manage and organize 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 analyze the behavior of a circuit design. Performing operating point, AC/DC sweep, or transient analysis simulations identify circuit performance issues without requiring a PCB prototype.
