Error: add_fileset_file: No such file <Quartus_Installation_Directory>/ip/altera/ethernet/alt_em10g32/MAC/synopsys/alt_em10g32.v

Due to a problem in Quartus® Prime software versions 15.1 and 16.0, the generation of Low Latency Ethernet 10G MAC IP simulation model may error out with the following message when using the Windows operating system.

Error: add_fileset_file: No such file <Quartus_Installation_Directory>/ip/altera/ethernet/alt_em10g32/MAC/synopsys/alt_em10g32.v
    while executing
"add_fileset_file synopsys/$file_name $filetype PATH synopsys/$file_name  {SYNOPSYS_SPECIFIC}"
    (procedure "sim_ver_mac" line 126)
    invoked from within
"sim_ver_mac $name"
    (procedure "sim_ver" line 3)
    invoked from within
"sim_ver alt_em10g32"

The work around for this issue is to disable the simulation file generation for VCS* and NCSIM* simulators manually in Windows environment. This can be done by modifying line (132~160) in <Quartus Prime installation directory>\ip\altera\ethernet\alt_em10g32\MAC\alt_em10g32_fileset.tcl
