| 9. | Since ic came forth , its evolution have almost accorded with the rule of moore . now the technology of ic had broken through the barrier of wire width at 100nm . with the condition of this , more and more problems of physical design of vlsi circuits change into np - hard problem
自从ic诞生以来， ic芯片的发展基本上遵循了摩尔定律，目前已经突破100nm大关，相应的系统规模的扩大，使得ic物理设计中的很多困难日益np问题日益棘手。 |
| 10. | Not only that but also the capacity of physical design of vlsi circuits itself do not catch up with the development of the technology of vlsi . for vlsi circuits , on the one hand many np - hard problems are impossible or very difficult to be solved by using traditional optimum algorithms ; on the other hand is that many new and specific deep sub - micron technology problems had not been considered , which will influence chip ' s performance
此外ic本身的物理设计能力一直落后同时代的制造工艺能力，于是就造成了下面的这种局面：现有eda工具难以应付复杂度呈指数增长的诸多vlsi物理设计难题，也缺乏对深亚微米工艺下一系列新问题（如：功率危机、复杂度危机和互连线危机）的考虑。 |
