摘要：
在本文中，我们研究的集成潜力，并探讨了低功耗热可靠的芯片上互连合成具有纳米光子波分复用（WDM）的设计空间。随着最近的进步，可以预见，纳米光子学由于其独特的功率效率，信号延迟和巨大的复用潜力，有望用于未来的片上数据信令。然而，在实现可行的片上集成之前，还有一些重大挑战需要解决。在本文中，我们提出了GLOW，一个混合的全球路由器，提供低功耗的光电互连综合热可靠性和各种物理设计约束，如光功率，延迟和信号质量的考虑下。GLOW的测试用例来自ISPD 07 -08全球路由基准进行评估。与贪婪方法相比，GLOW方法可降低总光功率约23%-50%，显示了片上WDM互连综合的巨大潜力。
英文摘要：
In this paper, we examine the integration potential and explore the design space of low power thermal reliable on-chip interconnect synthesis featuring nanophotonics Wavelength Division Multiplexing (WDM). With the recent advancements, it is foreseen that nanophotonics holds the promise to be employed for future on-chip data signalling due to its unique power efficiency, signal delay and huge multiplexing potential. However, there are major challenges to address before feasible on-chip integration could be reached. In this paper, we present GLOW, a hybrid global router to provide low power opto-electronic interconnect synthesis under the considerations of thermal reliability and various physical design constraints such as optical power, delay and signal quality. GLOW is evaluated with testing cases derived from ISPD07-08 global routing benchmarks. Compared with a greedy approach, GLOW demonstrates around 23%-50% of total optical power reduction, revealing great potential of on-chip WDM interconnect synthesis.
