执行命令ise-prog-prom在平台上合成vhdl时出现以下错误：
error:impact:2070 There are only 0 devices on the chain. Position 1 does not exists.
我试图在网上寻找答案，但到目前为止我没有运气。
有谁知道这个bug来自哪里，更好的是，如何修复它？
这是我的日志：

答案 0 :(得分：0)
生成此消息是因为您的程序员无法在链上找到任何JTAG设备进行编程。它没有连接到您尝试编程的设备。
如何对此进行故障排除很难说，我建议初学者确保程序员正确连接到主板上。如果你像我一样使用JTAG平台电缆II，这意味着编程器上的指示灯LED将亮起绿色（不是黄色）。然后我会刷新JTAG链。如果解决方案不是很明显，请查看this page是否对您有所帮助。
