NL5 is an analog circuit simulator working with true ideal and piecewise-linear components. Due to its unique algorithm, NL5 performs fast and robust simulation not distracted by convergence and other inherent SPICE problems. Both transient analysis and low signal AC response are available, including AC response for switching and digital circuits. NL5 is powerful and versatile, yet easy to use and user-friendly, with many unique features and capabilities. It is a perfect tool to prove the concept of a design, verify basic functionality of your schematic prior to proceeding with detailed analysis.
