在ISE里面调用ip核产生了25*18的乘法器，2级流水，然后再modelsim里面仿真时出现如下问题：
** Fatal: (vsim-3421) Value 1095521093 for use_dport is out of range 0 to 1.
# Time: 0 ps Iteration: 0 Instance: /multi/\multi_1/blk00000003 File: D:/software/xilink/ISE_DS/ISE/vhdl/src/simprims/primitive/mti/X_DSP48E1.vhd Line: 503
# FATAL ERROR while loading design
# Error loading design
这是怎么回事啊? 我加载的库有simprim，unisim ，xilinxipcore-lib
