AR# 982: Error 1140: the design contains X unresolved references
Error 1140: the design contains X unresolved references
XACT8000 returns the following errors when ran on an hierarchical .edif file created by Exemplar:
Error 1140: the design contains 4 unresolved references: LIST the sub-modules,
Error 1500: read: file 'toplevel.edif' doesn't contain a valid design.
When Exemplar compiles the VHDL code it names all of the sub-modules in UPPERCASE, but the default naming convention of files is lowercase. When XACT8000 can't find a sub-module in the original EDIF file (toplevel.edif), it searchs in the local directory and then along a variable called EDIF_SEARCH_PATH to try to find SUBMODULES.edif.
The way to solve this is to change your output file name in Galileo to UPPERCASE.edif or to move the lowercase.edif files to UPPERCASE.edif so that XACT8000 can recognize them.
