Cell <name> fed by <number> non-global control signals -- only <number> control sign
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.
how can i solve this problem?
My module has four input: clk,rst,din,cs and one output dout. clk frequency is unknown, I just choose four pins for each input signal and one pin for output signal ,but the compile error above occured.
