  • Variation factor assignment
    Patent number: 9129082
    Abstract: One or more embodiments of techniques or systems for variation factor assignment for a device are provided herein. In some embodiments, a peripheral environment is determined for a device. A peripheral environment is a layout structure or an instance. When the peripheral environment is the layout structure, a variation factor is assigned to the device based on an architecture associated with the layout structure. When the peripheral environment is the instance, the variation factor is assigned to the device based on a bounding window created for the instance. In this manner, variation factor assignment is provided, such that a first device within a first block of a die has a different variation factor than a second device within a second block of the die, thus giving finer granularity to variation factor assignments.
