After some time zooming around the schematic, I see what you mean about the sheer number of symbols. Have to agree that your program handles this size with ease. There was no delay (in my VM!) descending the blocks. I have been scrubbing the editor command cheatsheet on the repo.hu site and have no luck finding “ratsnets” type command. Is there some way to enable a connectivity view? That would enable me to trace the signal flow through the symbols without the need for organization or special presentation on the part of xschem. I could just highlight the net and trace manually through the gates.
