Module group, macrocell, standard unit synchronous layout convergence method and system for SoC integrated circuit automatic layout design

Abstract

The present invention belongs to the technical field of semiconductor micro-electronics, and in particular relates to a restraining method and a system of the synchronous layout of a module, a macro unit and a standard unit in the automatic layout design of an integrated circuit domain. Based on the fact that the soft module, the macro unit and the standard unit exist simultaneously, the system first produces a large group of initial layouts, conducts a layout of soft modules and macro units to the initial layouts and then carries out an assembled layout to the standard unit to generate a group of overall layouts. The group of overall layouts is evaluated, the small group of best evaluated overall layouts is taken as the next initial layouts, and then new layouts of soft modules, macro units and an assembled layout of standard units are carried out, a new round of layout evaluation is conducted, and a group of overall layouts with the best results is retained. A most appropriate overall layout is selected out by users as the starting point of the standard units to achieve the goal of rapid restraint, thereby achieving a rapid layout to the SoC integrated circuit that including a large number of macro units, soft modules and standard units and generating an integrated circuit layout which is provided with small layout area and high intercommunicating speed and is unrestricted by the circuit scale simultaneously.
