In recent years, process-induced mechanical stress has emerged as a useful manufacturing technique that enhances carrier transport and increases drive currents. This improvement in current has helped to compensate the decline of device scaling factors in parameters such as tox, Vth, and Vdd. In this work, we propose stress as a means to achieve optimal power-performance trade-off by combining stress-based, performance-enhanced standard cell assignment with dual-Vth assignment. We study how stress-induced performance enhancements are affected by layout properties and improve standard cell layouts so that performance gains are maximized. We then develop a circuit-level, block-based, stress-enhanced optimization algorithm that includes all layout-dependent sources of mechanical stress. By combining the two performance enhancement techniques (stress-based and dual-Vth) for a set of benchmark circuits, we find that our stress-aware optimization, decreases leakage by ~24% on average, for iso-delay, when compared to dual-Vth assignment. Similarly, for iso-leakage, our optimization algorithm reduces delay on average by 5%. In both cases, the proposed method only incurs a small area penalty (
