For one thing, parameters can be altered when you instantiate a model.
For example:

	module testparams;
	parameter p1 = 5;
	parameter p2 = 8;

	initial
	  begin
	    $write("p1 is %d, p2 is %d\n", p1, p2);
	  end
	endmodule


Now when you use it you can change the values of P1 and P2 like this:

	module junk;
	
	item1 testparams;
	item2 #(1, 2) testparams;
	item3 #(9,10) testparamsl

	endmodule

In the above example item1 will print out the original values of 5 and
8, item2 will print out values of 1 and 2, and item three will print
out values of 9 and 10 for the p1 and p2 parameters. RTFM, page 12-8
