Technology computer-aided design (technology CAD or TCAD) is a branch of electronic design automation (EDA) that models semiconductor fabrication and semiconductor device operation. The modeling of the fabrication is termed process TCAD, while the modeling of the device operation is termed device TCAD.
Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. [ 1 ] : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing.
Between the mid-1940s and 1950s, various developments were made in computer software.Some of these developments include servo-motors controlled by generated pulse (1949), a digital computer with built-in operations to automatically coordinate transforms to compute radar related vectors (1951), and the graphic mathematical process of forming a shape with a digital machine tool (1952).
One goal of CAD is to allow quicker iterations in the design process; [9] another is to enable smoothly transitioning to the CAM stage. [10] Although manually created drawings historically facilitated "a designer's goal of displaying an idea," [11] it did not result in a machine-readable result that could be modified and subsequently be used to directly build a prototype.

It is included with computer-aided design (CAD) and computer-aided manufacturing (CAM) in a collective term and abbreviation computer-aided technologies (CAx). The term CAE has been used to describe the use of computer technology within engineering in a broader sense than just engineering analysis.
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), [1] is a category of software tools for designing electronic systems such as integrated circuits and printed circuit boards. The tools work together in a design flow that chip designers use to design and analyze entire semiconductor chips.
Computer-aided technologies (CAx) [1] is the use of computer technology to aid in the design, analysis, and manufacture of products. Advanced CAx tools merge many different aspects of product lifecycle management (PLM), including design, finite element analysis (FEA), manufacturing, production planning, product Computer-aided design (CAD)
Computer Aided Industrial Design (CAID) is a subset of computer-aided design (CAD) software that can assist in creating the look-and-feel or industrial design aspects of a product in development. [1] CAID programs tend to provide designers with improved freedom of creativity compared to typical CAD tools.
