Abstract:
A method of transforming an integrated circuit design for fabrication with different design rules using a computer aided design system, the method comprising;defining a first set of logic circuit sub-components, which includes a plurality of logic circuit sub-components, each of the logic circuit sub-components being a functional and geometrical element of a logic circuit design, wherein the integrated circuit design is created from a plurality of logic circuit designs which include logic circuit sub-components selected from the first set of logic circuit sub-components, the sub-components conforming to a first set of design rules; defining a second set of logic circuit sub-components, which includes a plurality of logic circuit sub-components, each logic circuit sub-component of the second set of logic circuit sub-components corresponding to a respective one of the logic circuit sub-components of the first set of logic circuit sub-components, the second set of logic circuit sub-components conforming to a second set of design rules different from the first set of design rules; and replacing occurrences of each of the first set of logic circuit sub-components with the second set of logic circuit sub-components in the integrated circuit design, thereby transforming the integrated circuit design to a design conforming to the second set of design rules, wherein the length and width of the corresponding logic circuit sub-components in the first and second sets of logic circuit sub-components are the same.
