蒋介石打陈其美后人:SourceForge上有关Verilog/SystemVerilog/SystemC的开源项目

• 学EDA的同学可以通过开源提高自己

前两天和同学讨论说实验室里研究EDA的同学可以或参与或解读一些开源的项目来提高自己。

• 开源之于EDA

如今的电子行业已经离不开各种各样的EDA软件了。EDA(Electronic DesignAutomation)可以理解为供电子的企业级软件，为工程师提供服务的计算机辅助设计工具。如果你画过PCB板，或许你对这个名词就会有一个初步的认识。然而EDA工具远不止板级设计工具，这个名词现在更多地知道集成电路(IC)设计中使用的工具。从代码输入，综合，仿真，验证，布局布线，版图设计……它渗透到集成电路设计的每个环节。宏观的人和微观的晶体管之间如何沟通?那就是通过EDA工具了。我们期望能够高效地沟通，所以希望EDA工具越来越强大，只可惜它们的表现多少有些差强人意！

7月底在美国举行的2006年DAC上Cadence的前CEO，JoeCostello说在开源并不适合EDA行业，原因是从事这个行业的人太少，而开源需要大量散落在网络各个角落的工程师共同开发与推进。EDA市场是商业软件的天下，Cadence，Sysnopsys，MentorGraphics和Magma占有了绝大部分的市场份额。问题在于这个市场到达40亿美元就有些停滞不前了。全球其实有一陀陀的初创公司(Start-upcompanies)，有的成长得也还不错。然而很多人断言如Cadence等巨擎的地位不会被动摇。其实很多初创公司最后的结局就是被这些巨擎收购，前两天刚看到消息说一家台湾的EDA公司被Mentor收购了。这让我想起同学说“微软不用打败对手，只需要收买对手……”，呵呵！

全世界从事EDA软件开发的人有多少，我还不清楚！好像Synopsys全球也就千把人。不知道这样算来纯EDA软件开发人员全世界有多少，可能和很多其他领域的软件开发人员相比，真的很少。但我想全世界电子工程师的数量很多。美国每年高校培养70,000+70,000的电子工程师。中国、印度的数量现在更多。我想不能忽视他们在推动EDA发展上的力量。他们是EDA的用户，他们头脑中有这来自设计的第一手的需求！

• SourceForge上搜到的关于Verilog/SystemVerilog/SystemC的开源项目

我似乎有点扯了，闲话不多说。EDA相关的开源项目很多，由于我最近关心硬件相关的编程和建模语言，因此搜索了一下Verilog，SystemVerilog，SystemC相关的开源项目：
