在这里，我们通过对互连的明智和良好控制的处理来推进对基于拆分制造（SM）的布局的保护。首先，我们探讨SM的成本-安全权衡，这限制了它的采用。为了解决这个问题，我们提出了有效和高效的策略，以解除网BEOL。为此，我们设计了定制的“升降单元”，我们也提供给社区。此外，我们定义并推广了一个新的指标，网表恢复百分比（PNR），它可以量化对门级盗窃知识产权（IP）的弹性比既定指标更有意义的方式。我们广泛的实验表明，我们优于最近的保护计划的安全性。例如，我们将通常考虑的基准的正确连接率降低到0%，这在文献中是第一次。此外，我们诱导合理的低和可控的开销的功率，性能和面积（PPA）。同时，我们也帮助降低SM的商业成本。
Here we advance the protection of split manufacturing (SM)-based layouts through the judicious and well-controlled handling of interconnects. Initially, we explore the cost-security trade-offs of SM, which are limiting its adoption. Aiming to resolve this issue, we propose effective and efficient strategies to lift nets to the BEOL. Towards this end, we design custom “elevating cells” which we also provide to the community. Further, we define and promote a new metric, Percentage of Netlist Recovery (PNR), which can quantify the resilience against gate-level theft of intellectual property (IP) in a manner more meaningful than established metrics. Our extensive experiments show that we outperform the recent protection schemes regarding security. For example, we reduce the correct connection rate to 0% for commonly considered benchmarks, which is a first in the literature. Besides, we induce reasonably low and controllable overheads on power, performance, and area (PPA). At the same time, we also help to lower the commercial cost incurred by SM.
