华为韬定律PPT分享
今日，华为┏定律分享，其主要思路是在硬件缩放遇到瓶颈时，采用协同优化策略，实现从设计端到制造端共同实现芯片性能提升。这里要讲一下软硬件的设计思路。
软件硬件的相互掣肘，是制约计算机性能的重要原因。在硬件性能尤其是芯片性能受到限制时，人们往往会把软件编程的硬件利用率与效率发挥到极致，例如，NASA发射的旅行者号的其总存储容量还不如现如今的一个手机。但是其依旧可以完成负责的工作流。但是，随着硬件按照摩尔定律的发展，每两年翻一番，存与算不再是制约软件运行的难点，因此，软件中出现了类似于“库或者单元”的概念出现，我们不再依靠手动写代码实现某个功能，而仅仅是调用某个库就可以实现软件功能。但是，这种方式的运行效率会很低，（指的是执行一条命令所消费的资源，个人见解，错误误喷）。
硬件尤其是芯片也一样的变化趋势，为了实现设计的高度自由化，大部分设计都是利用某些别人已经封装好的库，仅仅需要库之间的排列组合，然后将其交给制造厂，例如中芯国际与台积电等，这样功能就可以实现了。而制造厂仅仅需要把基本单元晶体管做的越小越好，告诉设计公司的设计最小容限，做单元的公司只需要利用这些设计规则，设计符合需要的小单元，交给做大芯片公司即可。
在这里，面临的一个最大的优点与难点都展现出来，设计与制造的完全分离，简化了研发难度，但是，当随着摩尔定律进入到深水区，制造公司无法进一步缩小器件，实现性能翻倍，那么，这条传送链条会断裂，软硬件都会陷入到瘫痪，进入 more than moore， 在这其中，有两条解决思路：1，软件优化，应该依靠现有计算能力，深挖计算机潜能，在现有平台实现效率最大化。2. 硬件制造：单元设计+晶圆厂制造协同优化，通过优化芯片布局以及走线，榨干现有制造能力下芯片性能极限。其中可能包括 3DIC，先进晶圆级封装等等。
总的来说，还是生产力与生产关系之间这个逻辑，要提高收益，要么榨取剩余劳动价值，要嘛研发新设备，提高生产效率。当然比喻可能不恰当，个人观点，别喷呀。
