parametrized bufif

Hi,

I would like to parametrized a module in verilog that will instantiate a "x" number of modules.. below is and example of what I am trying to do..

Could someone show me the right way of doing this.. you could edit the example below and send me the corrected module if you can..

module tri_stat_param

#(

parameter ffsize = 8

)

(

in,

oe,

out

);

input oe;

input [(ffsize-1):0] in;

output [(ffsize-1):0] out;

tri [(ffsize-1):0] out;

bufif1 b1(out, in, oe); /* need to instantiate this keyword 'ffsize' */

endmodule

    Use a generate. 

    genvar n;
generator for(n = 0; n < ffisze; n = n+1) begin : gen_buffer
bufif1 b1(out, in oe);
end 
endgenerate

    That said.. this should do the same thing. 

    assign out = oe ? in : {ffsize{1'bz}};
