The Autoplacer is a program from the field of electronics design for the automatic positioning of the circuit elements during the physical circuit board , MCM / SiP and IC design (cf. circuit board disentanglement , chip design ). The autoplacers are usually embedded in an ECAD design environment and, unlike the autorouter, are rarely available as a separate program. The basis of the auto placers, which solve a mathematical optimization problem of the layout or the arrangement (see floor planning ), is based on the algorithms of combinatorial optimization . Like autorouters, autoplacers often do not produce layouts that are "immediately" satisfactory. In most cases, further manual interventions and adjustments are required. Rules that are difficult to specify, such as the EMC- related orientation of certain components relative to one another, often have to be observed . Measured against the very mature auto routers, today's auto placers are considered to be relatively underdeveloped for circuit board design.
