=====Definition and Purpose=====
::'''Computer-Aided Design (CAD)''' refers to software that enables users to create, modify, analyze, or optimize designs in various fields such as architecture, mechanical engineering, and manufacturing. CAD is predominantly used for designing physical structures and components. It allows designers to visualize objects in two-dimensional (2D) or three-dimensional (3D) formats, facilitating precise planning and adjustments before production begins1begins.
::In contrast, '''Electronic Design Automation (EDA)''' encompasses a suite of software tools specifically tailored for the design of electronic systems. EDA is crucial in industries like semiconductor manufacturing and printed ::circuit board (PCB) design. It focuses on automating the processes involved in designing electronic circuits at various levels—from high-level architectural descriptions down to detailed layouts.
