MICRO CELL GENERATION METHOD AND METHOD FOR DESIGNING MICRO CELL BURIED TYPE GATE ARRAY

摘要

PURPOSE: To increase integration. ;CONSTITUTION: Parameter values are inputted to a cell compiler to generate a micro cell, the empty region in the generated micro cell is recognized, and a unit cell block 15 or a sub macro cell for generating the mask pattern of an arbitrary logic circuit by the wiring between unit cells is arranged at the empty region. This sort of micro cell is arranged on a chip design region, a basic cell array is arranged at a region other than the micro cell on the chip design region, and the unit cell block in the macro cell is utilized as an expansion region of a basic cell array.;COPYRIGHT: (C)1997,JPO
