Global routing is an important link in Very Large Scale Integration (VLSI) design.As the best model of global routing, X-architecture Steiner Minimal Tree (XSMT) has a good performance in wire length optimization.XSMT belongs to non-Manhattan structural model, and its construction process cannot be completed in polynomial time, so the generation of XSMT is an NP hard problem.In this paper, an X-architecture Steiner Minimal Tree algorithm based on Multi-strategy optimization Discrete Differential Evolution (XSMT-Mo…
