求翻译：随着IC制作和设计水平的提高，进入VLSI时代，已能够将一个复杂系统集成到一个芯片之中。因此，VLSI芯片设计不仅要进行电路设计，还要进行VLSI系统设计。对于自行设计VLSI芯片的用户来说，其主要侧重点放在系统设计上。VLSI系统设计的首要任务是解决VLSI设计的复杂性问题。因而VLSI设计方法学的研究得到广泛的重视。当然对于困难的IC设计，也需要考虑众多的细节问题，多层次的抽象、多指标成本标准和成本指标间的冲突、有限的设计时间等等，都是IC设计者需要考虑的问题。是什么意思？

Ic production and design standards into the vlsi era has been able to integrate a complex system into a single chip. Vlsi chip design not only circuit design, but also for vlsi system design. For users to design vlsi chip, its main focus on the system design. vlsi system design, the primary task is

As IC production and design level, go to VLSI era, have been able to bring a complex system into a single chip. Therefore, VLSI chip design not only to make a circuit design, but also to VLSI system design. For self-designed chip VLSI user, his main focus is on the system design. VLSI System Design'

With increased levels of IC manufacture and design, into the VLSI era, has a complex system can be integrated into a single chip. Therefore, VLSI chip design not only for circuit design, VLSI system design also. F
