LTSpice

LTspice is a free electronic circuit simulation software used by engineers and hobbyists to design and analyze circuits virtually. It allows users to create digital models of electronic components and connect them to see how the circuit behaves under different conditions, such as voltage, current, and frequency. This helps identify potential issues, optimize performance, and reduce the need for physical prototypes. By simulating real-world electronic behavior accurately before building, LTspice saves time and resources in developing electronic devices and systems.
