我用QuartusII做的一个简单设计,在编译完成后出现下列对话框: File_mydesign_time_limited.sof contains one or more time_limited megafunctions that support the OpenCore plus feature that will not work after the harework evaluation time expires. Refer to the massages windows for evaluation time details. 无法下载到目标板上,消息窗口如下: Info: Started Full Compilation at Fri Mar 30 09:55:43 2007 Info: Ended Full Compilation at Fri Mar 30 09:58:45 2007 Info: SRAM Object File mydesign_time_limited.sof contains time-limited megafunction that supports OpenCore Plus feature -- Vendor: 0x6AF7, Product: 0x00A2 Info: Started Programmer operation at Fri Mar 30 10:03:06 2007 Info: Configuring device index 1 Info: Device 1 contains JTAG ID code 0x020B40DD Info: Configuration succeeded -- 1 device(s) configured Info: Successfully performed operation(s) Info: Ended Programmer operation at Fri Mar 30 10:03:08 2007 不知怎么回事?哪位高手指教一下,谢谢~~~ |
