Does Verilog have generic map like VHDL?

I am a beginner of Verilog. I am trying to build an N-bit-comparator. 
But I found no information for any generic map. I know in VHDL I can do

generic (N: integer:=4);

so that I can modify bits when I want to use this block.

If there is anything in Verilog that is similar to generic map in VHDL, 
it will help save me lots of work.
