回复 100#lordlion
您好,请教一下DDR2控制器。我调用DDR2 IP核,一旦例化到工程中,就会出现各种问题。请问您知道例化后需要做哪些修改吗?特别是UCF文件。有一个错误完全不知道什么意思,敬请指教,非常感谢。错误如下:Incomplete connectivity. The pin <PAD> of comp block <DDR2_B/u_ddr2_infrastructure/clk200_n> is used and partially connected to network
<DDR2_B/u_ddr2_infrastructure/clk200_n>. All networks must have complete connectivity to the comp hierarchy and the
connectivity for this pin must be removed or completed.
