Concluding Remarks And Future Work

In this chapter, we give concluding remarks and discuss some future research directions. We have presented a novel multilevel full-chip router, namely mSIGMA for SIGnal-integrity and MAnufacturability optimization in this book. To handle both the signal-integrity and manufacturability problem, we incorporate an intermediate stage of layer/track assignment into the multilevel routing framework. This intermediate stage not only speeds up the runtime, but also provides a suitable stage for doing optimization. Furthermore, we have adopted this novel multilevel routing framework to consider crosstalk, performance, and antenna effect problems, and the experimental results have shown that our approach is efficient and effective. In order to take advantage of the X-architecture, we also adapt our multilevel routing framework on the X-based architecture. The experimental results show that our approach is capable of handling diagonal segments well.
