点Programmer后提示：
File d:/experimentboard/nopain/niossmall_time_limited.sof contains one or more time_limited megafuntion time expires.Refer to the messages
window for evaluation time details. 点确定，下载完sof文件后，出现了如图所示的提示：click concel to stop using opencore plus ip点击concel后，试验箱中不在进行程序的运行。问题出在那里呢？是license的问题么？如何解决啊？
还有前面提到的双永管脚绑定的问题：我用的Altera 的cyclone ep1c6q240c8，将其
24号管脚及37号管脚与PIO输出绑定后，进行编译时，出现如下提示：
Info: Device migration not selected. If you intend to use device migration later, you may need to change the pin assignments as they may be incompatible with other devices.

我看了一下：Assignment ->devices->devices &pins->双用引脚无法进行配置。而
公司发过来的例程中却可以啊？[em27]作者: iceworld 时间: 2005-5-10 01:27

我是初学者，用的是quartus2 4.0和NIOS open-core plus development kit 3.10
编译时报错为
Error: Can't find feature line for core 6AFA_1001 in current license
Error: Can't compile design containing encrypted file C:/quartus/example0/sopc_parameters_0.tdf -- current license does not allow this file to be opened
Error: Node instance the_sopc_parameters_0 instantiates undefined entity sopc_parameters_0
请问是NIOS license 的问题吗？怎么解决？作者: roxette1979 时间: 2005-7-25 18:06
