已知球面上的离散点，我假设球心坐标为（a,b,c），半径为r我是用把球面方程转化为x^2+y^2+z^2=SS=r^2-(a^2+b^2+c^2)+2ax+2by+xcz也就是类似于y=a0+a1

我正在使用Vivado 2015.4与Windows 10操作系统一起工作。直到今天早上，这工作还算不错。现在我得到以下综合错误：[Common 17-345]找不到功能'Synthesis'和/或设备'xc7z020'的有效许可证。请运行Vivado许可证管理器以获取有关确定哪些功能和设备已获得系统许可的帮助。解决方案：在Vivado许可证管理器中检查许可证的状态。对于调试帮助，请搜索Xilinx支持“许可常见问题解答”。之后我检查了我的许可证状态，但我找不到任何不寻常的东西。这有点奇怪！谢谢以上来自于谷歌翻译以下为原文I am working as mentioned with Vivado 2015.4 with windows 10 operational system. That was working pretty good till today morning. Now i am getting the following synthesis error : [Common 17-345] A valid license was not found for feature 'Synthesis' and/or device 'xc7z020'. Please run the Vivado License Manager for assistance in determiningwhich features and devices are licensed for your system.Resolution: Check the status of your licenses in the Vivado License Manager. For debug help search Xilinx Support for "Licensing FAQ". After that I checked my license status, but i could not find any unusual thing. That is a little bit strange! Thank you
