Circuit diagrams are intricate networks made up of various elements, each serving a specific purpose to enable devices to operate. Crafting such diagrams is not a task for everyone, as it demands a solid understanding of electrical systems. For advanced users, tools like NL5 provide a reliable platform for designing and testing electric circuits.

EDA (Electronic Design Automation) technology makes good use of the characteristics of large computer storage and fast operation speed, can carry out simulation evaluation, design inspection, design optimization, data processing, and so on jobs on the design scheme that are difficult to complete manually. It has become the main technical means of integrated circuit, printed circuit board, electronic complete machine system design, and has been widely used.
