    摘要： Method, system, computer, etc., embodiments receive an original integrated circuit design into a computerized device. The methods herein automatically replace at least some of the original cells within the original integrated circuit design with replacement cells using the computerized device. Each of the replacement cells has an initial cell size that is unassociated with any specific design size. The methods herein automatically change the original design size of the integrated circuit design to a changed design size, and automatically individually change the initial cell size of each of the replacement cells to different sizes. At least two different replacement cells are changed from the initial cell size by different size reduction amounts based on different amounts of space required within the changed design size for each of the replacement cells.

    摘要： Approaches are provided for fixing pin mismatches from swapping library cells in layout migration. Specifically, a method is provided that includes collecting information about a first technology pin from a library cell in a first technology. The method further includes swapping the library cell in the first technology with a library cell in a second technology. The method further includes collecting information about a second technology pin from the library cell in the second technology. The method further includes building a pin-mapping table that is configured to map the first technology pin to the second technology pin. The method further includes scaling a layout from the first technology to the second technology. The method further includes modifying the layout based on the pin-mapping table to match the at least one first technology pin to the at least one second technology pin while satisfying ground rules of the second technology.
