Abstract
Standard cell libraries include one or more standard cells and one or more corresponding standard cell variations. The one or more standard cell variations are different from their one or more standard cells in terms of geometric shapes, locations of the geometric shapes, and/or interconnections between the geometric shapes. The exemplary systems and methods described herein selectively choose from among the one or more standard cells and/or the one or more standard cell variations to form an electronic architectural design for an electronic device. In some situations, some of the one or more standard cells are unable to satisfy one or more electronic design constraints imposed by a semiconductor foundry and/or semiconductor technology node when placed onto the electronic device design real estate. In these situations, the one or more standard cell variations corresponding to these standard cells are placed onto the electronic device design real estate.
