Hierarchy Descent/Ascent

mpee

Hi Matthias,

I am using this script you provided to descent into layout hierarchies:

lv = RBA::LayoutView::current
lv || raise("No layout opened")

sel_cv_index = nil
sel_cell = nil
lv.each_object_selected do |sel|
  sel_cv_index = sel.cv_index
  sel.each_inst { |i| sel_cell = i.inst.cell; break }
  break
end

lv.cancel

if sel_cell
  cv = lv.cellview(sel_cv_index)
  cv.cell = sel_cell
  lv.zoom_fit
end

This works nice, but I am also looking for a way to step back "UP" to the parent cell...
Can you help me here?

Thanks,
Martin

That is difficult in the general case, because there is more than one parent.

But why not just using "Display/Descend" and "Display/Ascend"?

They do pretty much what Cadence does if that is what you're asking for. If you don't like the default key bindings and prefer "X", "Shift+X", "Shift+B", just redefine them in "Application/Setup" "Application/Customize Menu".

And before you come to the next question: Check out the "key binding targets" at the bottom of that list. They correspond to "Move" and "Clone" for example.

It was unkind of Brand X to make bindkeys
for the same action, different between
schematic/symbol and layout editors.
Still trips me up after decades.

@dick_freebird I know, I feel the same
