| 摘 要： | 可重用性是当今超大规模集成电路设计的必要元素。与传统的封闭源代码付费IP相比，开源硬件以共享设计文档和IP模块的方式为硬件设计的重用提供了更加彻底有效的解决办法。基于开源硬件的SoC设计方法以其开放性和灵活性正被越来越多的设计者所接受并付诸实用。该文对开源硬件的相关概念、意义、面临的问题及发展前景进行了较为详细的介绍，并以开源处理器的设计作为实例，对基于开源硬件的设计流程进行了深入的探讨。

| Abstract: | Reusability is the key element in today’s VLSI design. Open-source hardware provides a more thorough and effective way for design reusability than traditional charged closed-source IP by sharing its design documents and IP modules. And open-source hardware based SoC design method is being accepted and practiced by more and more designers. This paper introduces relative concepts, benefits, problems and perspectives of open-source hardware in detail, and discusses open-source hardware based design flow in depth by exampling an open-source processor design. |
