Abstract

Techniques that facilitate time-driven placement and/or cloning of components for an integrated circuit are provided. In one example, a system includes an analysis component, a geometric area component and a placement component. The analysis component computes timing information and distance information between a set of transistor components of an integrated circuit. The geometric area component determines at least a first geometric area of the integrated circuit and a second geometric area of the integrated circuit based on the timing information and the distance information. The placement component determines a location for a latch component on the integrated circuit based on an intersection between the first geometric area and the second geometric area.
