Question on multiplier generated by ISE 10.1

hi, everyone!

in my project, i generate a complex multiplier by IP core. but when i simulate in modelsim 6.3c, an error appears. it says "Module 'CMPY_V2_1' is not defined". i have no solutions to it.

is there someone to give me some suggestions ?

 

thank you very much!

可能是Modelsim中没有你用到的IP核的库文件。

可是我已经编译添加了Ｘｉｌｉｎｘ的Ｍｏｄｅｌｓｉｍ仿真库了。
