Harmless: A warning that you didn't specified default values for the

This looks fishy. Try to understand what the author wanted to do. Probably
the syntax is problematic.

"no driver" means that you use a signal where there is no gate that provides
the output. Probably some typing error.
"no load" means that some signal is generated, but never consumed.
Try to understand all those issues.
