I am invoved in a design that has multiple derivatives.
So the same CPU ports are connected to the same DDR, same CPU ports connected to data flash etc.
Same power IC etc, etc.
Whenever there is a small change, I have to open all the schematics and change one by one.
Can I have just one design file which the other designs refer to.
You make the change once in that design file and the others automatically get updated.
