Schematic-based layout migration

A method comprising:

• receiving an original integrated circuit design associated with an original technology into a computerized device, said original integrated circuit design having an original design size and comprising a plurality of original cells, each of said original cells comprising an individual grouping of integrated circuit devices performing a logical function;
• automatically replacing at least some of said original cells within said original integrated circuit design with replacement cells to migrate said integrated circuit design to a different technology using said computerized device, said replacement cells having corresponding logical functions to said original cells that said replacement cells replace, each of said replacement cells having an initial cell size that is unassociated with any specific design size;
• automatically changing said original design size of said integrated circuit design to a changed design size using said computerized device;
• automatically individually changing said initial cell size of each of said replacement cells to different sizes to produce a migrated circuit design using said computerized device, such that at least two different replacement cells are changed from said initial cell size by different size reduction amounts based on different amounts of space required within said changed design size for each of said replacement cells;
• and
• automatically outputting said migrated circuit design from said computerized device.

A computer storage device comprising a non-transitory, computer-readable storage medium storing instructions executable by a computer to perform a method comprising:

• receiving an original integrated circuit design into a computerized device, said original integrated circuit design having an original design size and comprising a plurality of original cells;
• automatically replacing at least some of said original cells with replacement cells within said original integrated circuit design using said computerized device, each of said replacement cells having an initial cell size that is unassociated with any specific design size;
• automatically changing said original design size of said integrated circuit design to a changed design size using said computerized device;
• and
• automatically individually changing said initial cell size of each of said replacement cells to different sizes using said computerized device, such that at least two different replacement cells are changed from said initial cell size by different size reduction amounts based on different amounts of space required within said changed design size for each of said replacement cells.
