ソリューション

This problem has been fixed in ISE version 8.1i.  

 

For earlier ISE revisions, the problem can be avoided by setting the environment variable: 

 

WIndows: 

SET XIL_MAP_ENABLE_OLD_SLAVE_IPAD=1 

 

Linux and Solaris: 

setenv XIL_MAP_ENABLE_OLD_SLAVE_IPAD 1 

 

For general information about setting ISE environment variables, see (Xilinx Answer 11630).
