New layout requirements for memory, mixed-signal design

Keywords:memory  mixed-signal design  shape-based  layout automation 

New layout requirements and routing in the nanometre age are forcing a fundamental shift in layout automation techniques. This shift is a move from the traditional gridded approach to placement and routing to the more general and flexible approach of gridless or so-called "shape-based" techniques.

IC designers are looking increasingly to shape-based technologies. This technology can handle the extreme and often conflicting constraints—geometrical, timing, electrical, yield—that demand careful attention to an incredible amount of detail and flexibility. It offers a quality more akin to the "art" in full custom layout.
