ソリューション

A fix is now available to correct this problem in 1.5i Service Pack 2:

http://www.xilinx.com/txpatches/pub/swhelp/M1.5i_updates/15i_sp2_fpga3_pc.zip

CAUTION: This FTP Update is intended as a fast response for the issue
mentioned only. The risk inherent in this fast response is that there
is not enough time or resources available for the full regression testing
that is done for the Service Pack Updates and there is a higher risk of
introducing new problems. It is recommended that customers always install
the latest Service Pack Update, but only install FTP Updates when needed to
resolve specific issues.

This file is compatible with 1.5i Service Pack 2 only and should be installed
after the 1.5i SP2 Implementation Tools Update has been installed.
