  • Patent number: 9239902
    Abstract: A method of preparing a layout for manufacturing an integrated circuit chip according to a circuit design, the method includes generating a pattern for the layout based on the circuit design, determining, by a processor, if at least one layout rule is violated by including the generated pattern in the layout and modifying the layout if the at least one layout rule is violated. The at least one layout rule includes a constraint on a relationship between a power line pattern and a device pattern in the layout. The at least one layout rule is specified by comparing a predetermined threshold value with one of an estimated voltage drop along a signal path in a second layout different than the layout or an estimated current density on the signal path in the second layout. The constraint includes a minimum number of contacts per device or power vias per device.
