13 years agoThe Quartus top level entity must be the name of the top module not the name of its file. e.g. if the file "Lab1.v" starts with:
"module part1 (SW, LEDR);" then the top level entity must be "part1" not "Lab1.v"! Or you can just name the top module the same as its file name to make the problem go away.
