求助xilinx spartan6 倍频的方法
最经在用红色飓风spartan 6做项目,要把50MHz的倍频到200MHz,用的软件是ISE12.2,在ip核里没有6的ip,别的系列的ip核不能用,选中后下一步灰的,不能操作,怎么解决啊?
xilinx时钟资源分配方法共有5种:
(1)single clock pad --> IBUFG --> BUFG --> clock distribution
(2)differential clock pad --> IBUFGDS --> BUFG --> clock distribution
(3) single clock pad --> IBUFG --> DCM --> BUFG --> clock distribution
(4) logic --> BUFG --> clock distribution
(5) logic --> DCM --> BUFG --> clock distribution
不知楼主时钟是怎么连的,以上可参考一下
