Answers Database FPGA / Design Compiler 1999.05: Using SYNLIBS settings produces warning UISN-26 Record #5706 Product Family: Software Product Line: Synopsys Product Part: xsi-libs Product Version: 2.1i Problem Title: FPGA / Design Compiler 1999.05: Using SYNLIBS settings produces warning UISN-26 Problem Description: Urgency: Standard General Description: Beginning with Synopsys Compiler version 1999.05, the following warning may be seen while reading in library files specified by the "synlibs" program: Warning: The following synthetic libraries should be added to the list of link libraries: 'xdw_spartanxl'. (UISN-26) The library listed is in .sldb format and is normally listed only in the synthetic_library listing. Solution 1: According to Synopsys, this warning can be safely ignored. However, to make the warning go away, you can simply add the specified .sldb synthetic library to the link_library listing. For a Spartan XL, your libraries would look like this: link_library = {xprim_s20xl-4.db xprim_spartanxl-4.db xgen_spartanxl.db xfpga_spartanxl-4.db xio_spartanxl-4.db xdw_spartanxl.sldb} /* <---- the library is added here */ target_library = {xprim_s20xl-4.db xprim_spartanxl-4.db xgen_spartanxl.db xfpga_spartanxl-4.db xio_spartanxl-4.db} define_design_lib xdw_spartanxl -path /home/davidd/synopsys/synlib/syn9802/synopsys/libraries/dw/lib/spartanxl symbol_library = {spartanxl.sdb} synthetic_library = {xdw_spartanxl.sldb standard.sldb} End of Record #5706 - Last Modified: 11/17/99 15:22
