quartus ii 问题下载sof文件问题e

为什么我生成的是time_limited.sof文件呢？然后下载到板子时提示limited.sof contains one or more time_limited megafunctions that support the opencore plus feature that will not work after the hardware evaluation time expires.Refer to the Messages window for evaluation time details，然后我选择可以，但是程序没法运行，为什么啊？

Answer 1

你用到的某些IP如果没有license的话只能做评估 有时间限制
Altera文档解释了这个问题 在google搜索OpenCore Plus Evaluation of Megafunctions

You need to purchase a license for the megafunction only when you are
completely satisfied with its functionality and performance, and want to
take your design to production

Answer 2

assignments--device--device
and
pin
iptions,在configuration选项卡，钩上use
configuration
device并选择你使用的配置芯片。。。我用的8.0版，设置可能会有不同。
还有你检查下有没有生成pof文件？如果没有就可能是破解问题。
