Description

"Electronic design automation (EDA) is the category of tools for designing and producing electronic systems ranging from printed circuit boards (PCBs) to integrated circuits. This is sometimes referred to as ECAD (electronic computer-aided design) or just CAD. (Printed circuit boards and wire wrap both contain specialized discussions of the EDA used for those.)"
