: ProPilot (for commercial environments) and ProTutor (for education) serve as built-in EDAi design assistants. These tools analyze your active schematic layouts, calculate circuit metrics, suggest components, and write MicroPython scripts.
Electronic design automation (EDA) requires software that seamlessly bridges the gap between schematic capture and PCB layout. Labcenter Electronics has long been an industry leader with its Proteus Design Suite. With the release of Proteus 9.1, engineers, students, and hobbyists gain access to enhanced simulation capabilities, smarter routing tools, and more robust microcontroller simulation.
