This versatile circuit simulator allows you to intuitively design electronic circuits and analyze their performance. The program features a comprehensive library of components: resistors, voltage sources, diodes, transistors, LEDs, and bridge circuits, each with their own electronic properties. A dedicated module for calculating circuit and RF parameters supports manual value entry for precise modeling. The tool distinguishes itself from alternatives like KiCad through its deeper specialization in simulation and extended functionality for engineering calculations.
