Once the dominant tool for simulating dynamical systems,
analog computers faded from use in the 1960s and 1970s. These physically large
systems were time consuming to program and required a great deal of user
expertise. Nonlinear partial differential equations, stiff systems of ordinary
differential equations and stochastic differential equations are still
potentially time consuming to simulate on a digital computer. Modern analog VLSI
allows for the design of electronically programmable, tunable, small, and
lowpower analog computers, thereby eliminating many of the problems that
plagued conventional analog computers.
