Cadence OrCAD X and Allegro X is a professional electronic design automation (EDA) solution for engineers and PCB design teams. Developed by Cadence Design Systems, it provides comprehensive tools for schematic capture, printed circuit board (PCB) layout, circuit simulation, and design analysis. The platform helps engineers streamline electronic design workflows while supporting the requirements of modern high-density, high-speed, and standards-based circuit boards.
OrCAD X offers an intuitive PCB design environment featuring the OrCAD X Presto PCB Editor, while Allegro X combines schematic design, PCB layout, and analysis in an integrated 64-bit, multithreaded environment. Both solutions work with established Cadence technologies, including PSpice and Sigrity, to support circuit simulation and signal and power integrity analysis.
