IP : multiply accumulator v4.0 (abnormal results)

Hello,
 
I have been trying to use the Multiply Accumulator V4.0 IP.
I encountered a problem when I tried to simulate the module with ISE Simulator.
I reproduced exactly figure 2 described in the Multiply-Accumulator's datasheet, but I observe abnormal results.
I may do something wrong, but I really don't understand the result I obtain.
 
You'll find in the joint file "results_multiply_accumulator" :
- the results I obtain
- the TestBench I made
- the IP's parameters I entered
 
Moreover, could you please send me a correct TeshBench for the multiply accumulator v4.0 ?
 
Thank you for your help,
 
Emmanuelle, France.

It's best to submit a WebCase with Xilinx technical support to get help debugging a specific design or if you think there may be a problem with one of the tools.
