[PCB_FORUM] Re: Intelligent Dual Footprints 15.x

I have used modules several times, but only when using the Concept HDL
front end. Modules work great for placing a common circuit on several
different boards and the upper-level schematic symbol just displays the
interface signals to that circuitry. Each footprint that is place on the
board within the module will have a unique reference designator which
you can designate. Such as M1_R1, M1_C1, ets... Module two would have
M2_R1, M2_C1, etc....
But like I said, I've only performed this using Concept HDL into Allegro
Performance. Email me directly if you require further assistance.
Good luck.

This is the point I am trying to make. A module is just like a small
circuit board, if I am not mistaken. You still have the individual
components so your placement file would show each one. Once you
import it it acts like you placed and routed each component as
you normally would.
It is not a "symbol" per se. It is a subassembly.
