Abstract
A library group structured of logic gates and function blocks which allow all of the requirements of high speed operation, low power consumption, and high integration to be satisfied and a load driving capability to be optimally selected without need to rework and modify the placement and wiring design work is provided. A library group is structured of basic cells of transistors with a small channel width and has plural logic gates and plural function blocks which have the same logic function, the same size, and the same input/output terminal positions and which have different load driving capability. A portion which performs a logical function is separated from a portion which performs a load driving function. The portion which performs the load driving function is structured of a lateral type bipolar device or a hybrid mode device corresponding to SOI technology.
