Computer circuit engineering
Electronic circuits consisting of one or more integrated circuits are dealt with in micro-circuit engineering, which is the branch of microelectronics that is concerned with the designing of integrated circuits. In addition to the design and calculation of electronic circuits, microcircuit engineering deals with the problem of developing the structure of integrated circuits on the basis of the electronic circuits. The creation of a new integrated circuit is a complicated problem requiring the joint efforts of micro circuitry specialists, physicists, production engineers, and designers and the use of integrated experimental and theoretical methods, including the computer simulation of the circuit and its operating conditions. The theoretical basis of electronic circuit engineering (including micro circuitry) is provided by the theory of linear and nonlinear electric circuits, electrodynamics, mathematical programming, automatic theory, and so on. With the development of microelectronics, large-scale integrated circuits (LSI) are being created that constitute functional devices representing entire systems. Accordingly, electronic circuit engineering is in a number of respects merging with systems engineering.
