　　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 Design Automation)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，Joe Costello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，Mentor Graphics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-up companies)，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：

http://sourceforge.net/projects/covered
Covered is a Verilog code-coverage utility using VCD/LXT style dumpfiles and the design to generate line, toggle, combinational logic and FSM state/arc coverage reports. Covered also contains a built-in race condition checker and GUI report viewer.

·veri-indent
http://sourceforge.net/projects/veriindent
Veri-indent is a verilog source code Parser,Analyzer and Beautifier. (similar to c 'indent' , but more than that). Verilog source can be formatted and Symbol table, list of registers,wires,pli calls in source code can be extracted.

·Teal
http://sourceforge.net/projects/teal
TEAL - C++ multithreaded library to verfiy verilog designs

·Reed-Solomon Core Compiler

电子设计对于EDA工具的需求是很旺盛的！

但我作为EDA工具的消费者总觉得工具不够强大，又贵；
而EDA工具商们总是宣传说自己设计了多么好的软件，然后以高价叫卖！

不过EDA这个方向的开源社区的确需要培养
现在有人在Eclipse的平台上设计嵌入式设计的插件~使得Eclipse可以成为电子设计的平台，也得到了一些厂商的支持

EDA工具触及设计的各个角落，功能需求五花八门~
我觉得和物理设计相关的领域可能开源软件比较难进入，如和制造相关的EDA工具，因为开源的设计者无法与芯片制造企业合作得到很多物理制造的参数，没法为工艺建模，也无法得到大量样本的工艺库数据。其他很多方面是可以有所作为的！

特别是抓住新兴的功能需求，否则总是开发某种格式的读取查看工具、抑或代码编写和仿真工具就只能是模仿商用软件的份（不过如果做的好也是很有价值的）
