Does that mean, that no DS28E01 datasheet study is needed?
Just use DS28E01 as a "black box"?

Definitely yes.
You need to read the datasheet in order to learn that you need a 2.2k pullup resistor between onewire signal (DS28E01 pin 2) and 3.3V supply: but now I have told you :cool:, so you should not need the datasheet at all.
In the HDL code you only need to set your secure code key and possibly change the clock frequency.

What about hdl code - is it published somewhere or needed to be requested at Altera under NDA?

Request at Altera.
IIRC they don't require a NDA. They simply ask you generic details about your target application.
