vowstar@gmail.com Huang Rui YosysHQ/yosys This is a framework for RTL synthesis tools. It currently has extensive Verilog-2005 support and provides a basic set of synthesis algorithms for various application domains. Yosys can be adapted to perform any synthesis job by combining the existing passes (algorithms) using synthesis scripts and adding additional passes as needed by extending the yosys C++ code base. Yosys is free software licensed under the ISC license (a GPL compatible license that is similar in terms to the MIT license or the 2-clause BSD license). 这是一个针对RTL合成工具的框架。它目前广泛支持Verilog-2005，并提供一套 基础的合成算法用于多种应用领域。Yosys可以通过组合现有的合成脚本中的算法， 并根据需要扩展Yosys的C++代码库来添加额外的算法，从而适应任何合成任务。 Yosys是根据ISC许可证发布的免费软件，这是一种与GPL兼容的许可证，其条款与 MIT许可证或二条款BSD许可证类似。
