`include doubt

`include doubt

I want to use the o/p generated by a verilog code into another.
I am using `include "file name" but I am not able to get the value of the o/p in the current file. :(
The code is"

 `include "check.v"
module multiply(flag,ma, mb, mprod,  expa, expb, expprod,signa, signb, signprod);
input [22:0]ma, mb;
input[5:0] flag;
input [7:0]expa, expb;
input signa,signb;
output signprod;
output [46:0]mprod;
output [8:0]expprod;
reg [46:0]mprod;
reg signprod;
reg [8:0]expprod;
always @ ( ma or mb )
mprod = ma*mb;
signprod = signa^signb;
expprod = expa+expb;
if(mprod [flag*2] == 1)
signprod = signprod+1;

where flag is the O/P generated by the check.v file. But its being read as XXXX in this file.

Please help.


RE: `include doubt

If you want the output of module "check" to drive the input of module "multiply", you need to conect the two together at a higher level of hierachy.  For example:


module top;

wire flag;

check i0 ( .flagout(flag) );
multiply i0 ( .flag(flag) );
