Definition

Spice analysis is a simulation tool used in electronic circuit design to predict the behavior and performance of circuits by analyzing their response to different inputs. This technique is essential for engineers to evaluate circuit functionality, verify design assumptions, and optimize component values before physical prototyping. By applying Kirchhoff's laws and circuit theorems, spice analysis allows for comprehensive modeling of complex circuits, ensuring that designs meet specified performance criteria.
