Previous works do not handle three main issues for WRONoCs: correlations between the topological structure and physical layout, trade-offs between the maximum insertion loss and wavelength power, and a fully automated flow to generate predictable designs. As a result, the insertion loss estimation is inaccurate, and thus only suboptimal results are obtained. To remedy these disadvantages, we present a fully automated topological structure and physical layout codesign flow to minimize the maximum insertion loss and the wavelength power simultaneously with a significant speedup. Experimental results show that our codesign flow significantly outperforms state-of-the-art works in the maximum insertion loss, wavelength power, and runtimes. © 2020 IEEE.Automation; Computer aided design; Economic and social effects; Fiber optic networks; Insertion losses; Network coding; Network-on-chip; Programmable logic controllers; Topology; Fully automated; Physical layout; Predictable design; Signal transmission; State of the art; System on chip design; Topological structure; Wavelength routed optical networks; Integrated circuit layoutconference paper10.1109/DAC18072.2020.92186252-s2.0-85093980974
