请问我用的FPGA的时钟源和ODDR2的IP核可以用在cpld中吗？

我在Xilinx ISE中直接把原来用于FPGA的程序改为CPLD的了，直接改到器件，综合会出现错误：ERROR:NgdBuild:604 - logical block 'oddr2_inst' with type 'ODDR2' could not be
   resolved. A pin name misspelling can cause this, a missing edif or ngc file,
   case mismatch between the block name and the edif or ngc file name, or the
   misspelling of a type name. Symbol 'ODDR2' is not supported in target 'xbr'.

有那位大神知道吗？
