The approach to designing field-programmable logic arrays is not a one principle process. It consists of numerous steps that should be religiously followed in order to ensure that the design package contains the specific defined logic and that it does the job it was designed to do. The specific function neededmust be determined, also ensure that the FPGA (field programmable gate arrays) are compatible to the logic required and will perform its intended use. The stages of logic design are discussed further.

The utility of computer-aided design packages in the design of field programmable gate arrays is investigated with respect to other electronically programmable logic devices. Several factors related to the growing use of hardware description language and logic synthesistools for high-level graphical design are examined. It is shown that further developments in the two fields will focus on cost reduction plus enhancement ofspeed, density and device properties.
