So, can Anyone say anything with facts against using BDF editor?

[Altera_Forum]

Not really. I say use the tools you feel comfortable with. 

It's just that in my opinion it feels easier to use at the beginning, but as your design gets more complicated it resembles more and more like a plate of spaghetti and becomes near to impossible to debug properly. If you find reading someone else's code difficult, try to read someone else's design entirely done with the graphical editor, spread over 4-5 A3 sheets... real life experience! :shock:  And after 2/3 times of SOPC Builder / QSys messing your symbol completely even for a tiny change, you will be cured and will use HDL, like everyone else ;)

Also to add: 

- you cannot directly simulate graphical files, you need to export them to hdl (then you get into the problem of "what to I check into my version control system". You check both in, and you risk having the two missmatch each other because on the last checking you forgot to export the bdf again). - they are not parameterisable at a connection level (HDL is) -You can only open them in Altera tools  -You get called bad names by all the other engineers.

And I forgot: 

The BDF editor in quartus 10+ is really really cr ap. compared to version 9 and before. Its like they're really trying to stop people using it.

BDF editor and Qsys are different things. 

Basically they dont want you to use the BDF editor if you can avoid it.
