I'm trying to use the ENA pin of the cyclone IV using SystemVerilog. when ENA is 1, input data to register. 

 

 

But I can drage this pin out. isn't the mulpiler is driven by a clock? why we don't need to put a clock to drive the register in the mulpiler?

ENA is clock enable - you need a clock for it to work.
