Placement and simulation of cell in proximity to cell with diffusion break

Abstract:

A system and method for placement and simulation of a cell in proximity to a cell with a diffusion break is herein disclosed. According to one embodiment, an integrated circuit is designed to include a first cell that has a first edge and a second edge opposite the first edge. The first cell may also include a diffusion region that extends from the first edge to the second edge with a diffusion break separating the diffusion region. The diffusion break may be spaced away from the second edge by a distance that degrades a metric (e.g., a delay, a slew, dynamic power, or leakage) of a second cell placed next to the second edge beyond a threshold level.
