DE2-115 引脚分配经常出现“Some pins have incomplete I/O assignments”

RT，可是板子可以正常运行，警告如下：

Warning (15714): Some pins have incomplete I/O assignments. Refer to the I/O Assignment Warnings report for details
Warning (169177): 1 pins must meet Altera requirements for 3.3-, 3.0-, and 2.5-V interfaces. For more information, refer to AN 447: Interfacing Cyclone IV E Devices with 3.3/3.0/2.5-V LVTTL/LVCMOS I/O Systems.
        Info (169178): Pin CLK uses I/O standard 3.3-V LVTTL at Y2

谁遇到过解决了？ 求解！

好像是软件BUG，我也遇到过不能分配的问题，重新一个工程就好了
