[0018] Referring now to the drawings, several exemplary aspects of the disclosure are described. The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any aspect described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other aspects.
[0019] Aspects disclosed in the detailed description include systems and methods for process varying power control in three-dimensional (3D) integrated circuits (ICs) (3DICs). In an exemplary aspect, at least one process change sensor is placed in each layer of the 3DIC. The process variation sensors report information about velocity characteristics of elements within the respective layers to decision logic. The decision logic is programmed to weight outputs from the process variation sensors according to the relative importance of logical path segments in the respective layers. The weighted outputs are combined to generate a power control signal sent to a p...
