A Reconstruction Method of General EDA Model Layout Physical Connection Relationship

Abstract

The invention belongs to the technical field of EDA model layout simulation. Specifically, it is a method for rebuilding the physical connection relationship of a general EDA model layout, which establishes the interconnection relationship between stacks in the EDA model, the graphic connection relationship on each stack, and the graphic connection relationship on interconnected stacks. , after summarizing the connection relationships established above, establish the connection relationship of all the graphics in the entire model, and establish the physical connection relationship of each group of interconnected graphics, that is, the physical connection relationship of the overall EDA model layout. Transform the judgment of the connection relationship of the EDA model into the judgment of the intersection relationship of pure two-dimensional graphics; and use the separation method to reduce the time complexity of the intersection relationship of two-dimensional graphics, achieve the goal of quickly establishing the connection relationship, and solve the pre-processing of the layout in the simulation process The problem that it is impossible to accurately extract specific link information from the model ensures that users can smoothly extract signal or power integrity.
