问题描述

Vivado环境下Verilog代码综合是出错

[Common 17-345] A valid license was not found for feature 'Synthesis' and/or device 'xc7vx980t'. Please run the Xilinx License Configuration Manager for assistance in determining
which features and devices are licensed for your system.
是器件不支持还是licence无效，换器件还是出现同样的问题

解决方案

A valid license was not found
license无效。说的很清楚。
