我在Cyclone EP1C20里做了一块 RAM 用单片机对其进行读写 ,可是老是提示我
(Warning: TRI or OPNDRN buffers permanently enabled Warning: Node "data7~1" Warning: Node "data6~1" Warning: Node "data5~1" Warning: Node "data4~1" Warning: Node "data3~1" Warning: Node "data2~1" Warning: Node "data1~1" Warning: Node "data0~1")
'输出端Q 和输入端DATA—in 在和外部 连接时要共用 DATABUS'
如何解决啊? |
