Compaction (electrical engineering)

The compaction is an optional, often the final step in the layout design of integrated circuits and printed circuit boards , in which an optimized circuit layout, for example in terms of its generated surface area required.

Compacting is used either to optimize a layout (layout optimization) or to generate it (layout generation). In the first case, input data is a circuit layout (e.g. mask layout ) that is correct in accordance with the design rules , in the second application a symbolic layout with an abstract representation of all components (e.g. stick diagram ). In both cases, the aim of compacting is to achieve a layout arrangement with a minimal area while adhering to all design rules. In addition, modern compacting tools specifically optimize individual parameters of a circuit layout, such as B. signal transit times .
