delay a signal by several clk cycles in verilog

--- Quote Start ---

Hi,

Is there anyone knows an easier way to delay a signal by several clk cycles in verilog

I was trying to use repeat as below, however, it only works when I run RTL simulation, it will not work when I run gate level simulation.

data_out <= repeat (15) @(posedge clk ) data;

Thanks!!

It's called a SHIFT REGISTER. Google: shift register verilog code
