Hello everybody from rainy southern Germany,

I had the same issue, and the tool gives you no sort of

description what is wrong, I was missing my HDL file - it was not

defined. As posted below, just check under

Project - Add/Remove files in project. If you see no files listed

then that is the problem.

By the way, changing the severity of the error messages for HDL

input to level 3 did not give me any additional info. This could be improved in

my opinion. :confused:

Cheers,

Eric
