Hi,
While trying to do the Lab 6 from this website (URL: http://www.zedboard.org/course/introduction-zynq, under "Download Labs"), I get this error at Step 37 "[HDLCompiler 267] Cannot find port LED_DutyCycle on this module)" when I do Generate BitStream.
system_stub.v file is pasted below, any help would be highly appreciated.
