1. I love using BDF files because the only alternative that I know is implementing your entire design by code. IMHO it's much easier to see your design visually, how everything connects, all the pins, all the inner signals (nets), than seeing it by code. If I had done it by code (components) I would always wonder if I made some mistake.

Is there some other alternative that I may not know about? One where you can actually see the blocks and nets, like in a BDF file?

2. Thanks for the info! I did not know about these attributes, or even fan-out (shame on me), and by experimenting for a while I saw that a signal can really be unselectable or become red when it has no fan-out. You saved me a lot of confusion in the future :)
