8 years agoSince you're using the old version Quartus 5.x, you could download the Megacore library from here :
Windows : ftp://ftp.altera.com/outgoing/release/megacore_lib_51_pc.zip Linux : ftp://ftp.altera.com/outgoing/release/megacore_lib_51_linux.tar Unzip the files, install the Megacore libraries, or under the Windows folder , you will find the stsfrm-v2.4.0 folder. This is the SONET/SDH compiler you're looking for. Install it and check if it works for you.
