Avoid BDF editor like the plague

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.
