DSP48e utilization control in ISE

Hi,

 

How could I let ISE start to use other logic resource to do multiply only when all DSP48 resource are ran out? I just find one control method in HDL options (synthesis process properties - HDL options ), but it can not help my case. When Auto is seleted, the ISE will use other logic resource to do the multiply without using all the DSP resource. When Yes is selected, the required number of DSP48 will excceed the total available DSP48 number in my Virtex-6 FPGA.

 

Could anyone give some suggestions?

 

Thanks
