Electrical computer-aided design (ECAD) software systems are used to design and develop electronic systems such as printed circuit boards (PCBs) and integrated circuits (ICs). ECAD software enables electrical engineers to create and modify diagrams and layouts including 2D and 3D models. Electrical design is the process of planning and creating electrical equipment, such as electrical components, schematics, lighting equipment, power systems and telecommunications infrastructure. Autodesk electrical design and electrical control design software is built to address the specific workflows for electrical controls systems designers.
