Purpose of WIRE buffer in BDF

What is the purpose of the "WIRE" buffer in BDF schematics ? The reason for asking is related to the Verilog "WIRE", which I understand to be analogous to a VHDL "SIGNAL" (I don't know Verilog). ...

Hi,

--- Quote Start ---

In the schematics below, is there a difference between "circuit1" and "circuit2" ?

in1 ----|>----- out1 // circuit 1 - "|>" is a WIRE-buffer

in2 ------------ out2 // circuit 2

--- Quote End ---

There will be no difference.

So, if coding BDF, when and why sould the "WIRE" buffer be used ?

For example when changing names.
