Problems solved by technology

However, since no library view contains manufacturability attributes, variants produced by existing techniques do not provide options for specific manufacturability correlates
Moreover, existing commercial software that uses typical library views cannot extract or use manufacturability features for any design element in the library

Embodiment Construction

[0019] A number of specific structures, parameters, etc. are described below. It should be appreciated, however, that these descriptions are not to be construed as limitations on the scope of the invention, but rather are provided as descriptions of exemplary embodiments.

[0020] As mentioned above, design component libraries are generally used to design IC chips. Libraries include all required views of library design elements, including performance-related properties of library design elements. However, traditional libraries do not provide a library view with manufacturability attributes such as number of good dies per wafer (GDW) that can be predicted, yield related attributes. It should be recognized that manufacturability also includes various IC characteristics such as defects, printability, reliability, and the like. Manufacturability ultimately determines the yield of the design.

[0021] In one exemplary embodiment, library design elements are analyzed to determine...

Abstract

Library design elements (102) are analyzed for manufacturability to be used in designing an IC chip to be manufactured using a particular manufacturing process. The library design elements from a library are obtained. Manufacturability attributes (104) of the library design elements are determined for the particular manufacturing process, where manufacturability attributes include yield-related attributes. Library views (106) with manufacturability attributes for the library design elements are then generated, which are utilizing by an electronic design automation (EDA) tool.

Description

technical field [0001] The present invention relates to integrated circuit design, and more particularly, to integrated circuit design that optimizes manufacturability. Background technique [0002] The design of an integrated circuit (IC) chip consists of discrete design elements, also known as intellectual property (IP) elements, of various sizes and complexities. The smallest component is often called a standard cell. Larger assemblies of elements can be interconnected to produce complete functions, commonly referred to as blocks. Multiple blocks are interconnected to produce the fabricated IC chip. [0003] In order to design an IC chip, for a given manufacturing process, it is necessary to produce an assembly of such cells or blocks consistent with the particular manufacturing process, while providing a variety of functional and performance options that allow the designer to design and optimize a given IC chip. The assemblies of these units and blocks produced for a ...
