Modeling mechanical behavior with layout-dependent material properties

A computer system for design analysis comprising:

• a memory which stores instructions;
• one or more processors coupled to the memory wherein the one or more processors are configured to:
• obtain a design and integrated circuit structural information for the design;
• extract anisotropic information from the integrated circuit structural information;
• compute layout dependent material volume fractions using the integrated circuit structural information;
• determine anisotropic mechanical properties based on the anisotropic information;
• and
• calculate mechanical responses, based on interconnecting layers that undergo stress due to thermal coefficients of expansion, based on the anisotropic mechanical properties and the layout dependent material volume fractions.

• code for obtaining a design and integrated circuit structural information for the design;
• code for extracting anisotropic information from the integrated circuit structural information;
• code for computing layout dependent material volume fractions using the integrated circuit structural information;
• code for determining anisotropic mechanical properties based on the anisotropic information;
• and
• code for calculating mechanical responses, based on interconnecting layers that undergo stress due to thermal coefficients of expansion, based on the anisotropic mechanical properties and the layout dependent material volume fractions.
