COREGEN: Output of Delay Element module does not change in simulation if CE is unconnected
説明
General Description: Output of COREGEN Delay Element module does not change in simulation.
ソリューション
The Delay Element does not float its CE input to VCC if left unconnected. The signal tied to this pin is used internally to activate the WE pin of the RAM used to store the input to the Delay Element.
CE should always be tied either to VCC or to a control signal whose logic level is defined--it will not respond to a clock input unless its CE pin is driven to a logic 1 level.
