Next, the computer system assigns a second potential to other signal conductors included in the electronic circuit design layout. The computer system then selects a metal fill from the electronic circuit design layout, which is void from carrying an electrical signal, and generates a zero charge equation for the selected metal fill. The zero charge equation establishes that a total charge residing on the selected metal fill is equal to zero. The computer system includes the zero charge equation in a system of equations, which includes grid point potential equations, and solves the system of equations. In turn, the computer system computes capacitance values for the signal conductors based upon the system of equation solutions, and simulates the electronic circuit design layout using the computed capacitance values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Generating capacitance look-up tables for wiring patterns in the presence of metal fills","description":"A computer system selects a signal conductor from an electronic circuit design layout and assigns a first potential to the selected signal conductor.
