DTCO including Sustainability: Power-Performance-Area-Cost-Environmental score (PPACE) Analysis for Logic Technologies

Abstract

Driven by concerns on climate change, resources depletion, local and global pollution, sustainability is becoming an integral component of business and of regulations. The progress of Design Technology Co-Optimization (DTCO) methodologies and tools, building transversal knowledge from manufacturing to design, provides an opportunity to develop a framework for early sustainability assessments of logic technologies. Environmental scores can be derived together with the established Power, Performance, Area, Cost (PPAC) metrics. To demonstrate this approach, we evaluate the energy and water consumption as well as the greenhouse gas emissions trends from processing logic nodes from iN28 to iN3 with different scaling scenarios.
