General Description: The Alliance 2.1i synthesis, DesignWare and simulation libraries were compiled with Synopsys Compiler version 1998.08. 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 Alliance 3.1i synthesis libraries for Virtex and Virtex derivatives were compiled in Design Compiler version 1998.08. No changes were done to the CPLD, 4K, or 5K libraries, so the Alliance 2.1i/1998.08 libraries can be used.
The XSI 2.1i SP5 libraries compiled with Design Compiler 1998.08 have been placed on the Xilinx FTP site.
Extract this file in the $XILINX directory. The new libraries should overwrite the existing libraries in the $XILINX/synopsys/libraries directory.
This can be done by issuing the following commands:
mv a21sp5_9808_lib.tar.gz $XILINX cd $XILINX gunzip a21sp5_9808_lib.tar.gz tar xvf a21sp5_9808_lib.tar rm a21sp5_9808_lib.tar
