在过去10年里ASIC的逻辑门数目急剧地增加,以至设计人员无法应付其复杂性。问题已不再是单个IC是否有足够资源去容纳系统级的设计,而是设计人员如何跟上芯片复杂性增长的步伐。 对这个问题的解答在于可重用的知识产权(IP)。设计人员能够用好现有硅芯片的唯一方法是利用此前已经开发 The number of logic gates in ASICs has soared over the past decade that designers can not cope with their complexity. The problem is no longer whether individual ICs have enough resources to accommodate system-level designs, but how designers keep up with the increasing complexity of chips. The answer to this question is reusable intellectual property (IP). The only way designers can make good use of existing silicon chips is to exploit what they have already developed
