General Description: The Alliance 2.1i synthesis libraries were compiled with Synopsys Compiler version 1999.05. In order to use these libraries with an older version of Synopsys, you must have the libraries re-compiled with that version of Synopsys software.
The XSI Virtex-E libraries compiled with Compiler version 1999.05 have been placed on the Xilinx FTP site.
Extract this file in the $XILINX directory. The new libraries will be placed in the $XILINX/synopsys/libraries/syn directory.
This can be done by issuing the following commands
mv a21_virtexe_db.tar.gz $XILINX cd $XILINX gunzip a21_virtexe_db.tar.gz tar xvf a21_virtexe_db.tar rm a21sp5_virtexe_db.tar
