ISE MAP报错: Unsupported programming for BSCAN block and JTAG_CHAIN attribute value 1

具体报错信息如下:

PhysDesignRules:1683 - Unsupported programming for BSCAN block and JTAG_CHAIN attribute value 1. The BSCAN
   component disp_emif_for_feed_data/icon_2/U0/U_ICON/I_YES_BSCAN.U_BS/I_V6.ISYN.I_USE_SOFTBSCAN_EQ0.U_BS has placement
   which requires the JTAG_CHAIN attribute to be set to the value 2. The JTAG_CHAIN attribute must be changed or the
   programming for the BSCAN block must be moved to a location corresponding to the JTAG_CHAIN attribute setting.
ERROR:Pack:1642 - Errors in physical DRC.

解决方法:

参考http://china.xilinx.com/support/answers/36901.htm以及http://www.xilinx.com/support/answers/42858.htm,猜测可能是使用多个ICON核导致的。报错工程中确实使用了2个ICON核,将其中一个ICON核的BSCAN属性改为USER2,问题解决。
