对子模块编译出现
Error: Cell DatAMC[3]~reg0 fed by 5 non-global control signals -- only 4 control signals may be non-global
这个怎么解决啊
Its help says:
CAUSE: The specified cell is fed by the specified number of control signals that are non-global signals. However, the current target device only supports the specified number of non-global control signals.
ACTION: Assign the Global Signal option with a value of Global Clock to one of the clocks, or modify the design so that the cell is driven by less control signals such as clock or asynchronous clear.
怎么把时钟设成全局信号?
