A methodology for physical design automation for integrated optics

Advancements in silicon photonics technology are enabling large scale integration of electro-optical circuits and systems. To fully exploit this potential, automated techniques for design space exploration and physical synthesis for integrated optics must be developed. This paper investigates how conventional VLSI physical design automation techniques can be adapted for integrated optics applications.We present an overall methodology for cell-placement, global routing, and detail routing for physical synthesis of optical circuits. In addition, we highlight optics-specific constraint models, design rules and optimization criteria that will have to be accounted for in physical design automation.
