" Netlist generator could be merciful to me, when it would not have
found hierarchical information sheets"

I *fully* disagree.

About net names, the most important issue occurs when a net name used by
a zone is changed, for some reasons.

This is roughly was happens for you.

I spent a *lot of time* to try to fix this issue over the years, using
different ways.

Currently, it can happens, but the way net names are now built minimize
this possibility.

Having a netlister which changes its behavior when it founds (or not) a
hierarchy is reopen this can of worms.

The reason is due to the fact you can start you design without using a
sub-sheet, and later, create a hierarchy, for some reason.
When happens, the board will be broken.

I have some ideas to solve the netname zone issues, but I do not
volunteer to spend a lot of time just to remove one letter to the
netnames in some designs.
