According to the place and route location and layout of the restrictions to limit the sub-module, the design methods can be divided into full-custom and semi-custom two categories. Since raising the level of manufacturing technology, feature size decreases, the various parameters on the circuit parasitic effects also growing in the territory of the design of a growing number of issues to consider.
