Purpose

CAE/CAD tools for logic circuit design usually have the following functions:

• Design of a circuit in the form of a circuit diagram,
• Verification of the function,
• Simulation under different tolerance conditions,
• Generation of package and component libraries,
• Conversion of the circuit diagram to a layout,
• Manufacturing of exposure masks for production,
• Derivation of data that are important to production, such as parts lists and test plans.

Related to this is the design of programmable building blocks, such as gate arrays, GALs and other types of Programmable Logic Devices (PLDs). Programs for finite element analysis simulations have to be referred to as a special case of CAD development.
