一、引言 随着电子产品的激烈竞争,采用ASIC技术,运用EDA手段,自行开发、设计、制造电子产品,并不断更新换代,才能把握市场的主动权。 EDA技术最大的特点是硬件电路设计软件化,降低了硬件电路设计的难度,缩短了设计周期,由于对产品的更新、改进仅仅是程序的修改,顺应市场千变万化的潮流。而且EDA软件的PC化可使设计师从网上或EDA软件供应商处得 I. INTRODUCTION With the fierce competition of electronic products, ASIC technology, EDA means, self-development, design and manufacture of electronic products, and continuous upgrading can we take the initiative in the market. EDA technology is the biggest characteristic of the hardware design of the software, reducing the hardware design of the circuit and shorten the design cycle, due to product updates, improvement is just a program modification, to adapt to the ever-changing market trend. And PC-based EDA software enables designers to access the Web or EDA software vendors
