Hierarchies not the best for video pipelines

[Brad Smallridge]

Am I missing something? It seems that I am spending a lot of
time passing variables from subordinate routines to the top level
and then back down to the next subordinate routine where what
I really want is to send data from one subroutine to the next in
a pipeline fashion. Is there any way to do this?

If you are talking about procedure scope
in a testbench, see today's other threads.

If you are talking about synthesis code,
you can improve variable scope by
declaring all closely related variable objects
in the same clocked process.
