another wire inside of the macro. Now where is the resolution going to occur?
(OK, you can see in the above picture that is occurring at the adder input in
this particular case, but we know it might as well have occurred at another
point.)
Imagine for a moment that Thru was not a macro but a built-in module. In
that case, it’s obvious that the feedback resolution could not occur within the
module, it must occur outside.
Well, we are trying our best to make macros look and behave as if they were
built-in modules. For that reason by default, the resolution of feedback loops
will occur outside the macro. It’s not specified exactly where it will take place,
but it will take place outside of the macro.
As a general rule, feedback resolution occurs on the highest structure
level of the feedback loop.
However, you can change that behavior and allow feedback resolution to happen
inside the macros. In fact, you should have wondered, if macros are treated
the same as built-in modules, how can a Z^-1 macro resolve the feedback.
Consider the following structure:
If macros and built-in modules are the same then nothing should change when
we replace the multiplier by a Z^-1 macro:
But it is different, because the implicit feedback is now gone. There must be
something special about the Z^-1 macro. And, in fact, there is.
If we look inside this macro we’ll see almost the same structure as the one
we mentioned earlier to implement the Z^-1 functionality:
