I design in DESIGN ENTRY HDL circuit and I have there two separated global signals agnd and dgnd. I am planning in allegro PCB to create a isolation ditch like inductor so i must connect these to signal togather. My question is how? I try to do global shortcut as tool->option->output and then to connect it together in schematic (after saveing, i dont get any warning). I start netrev to packaging and then when i look at net report, there were agnd and dgnd too. So i go back to schematic and i try to use alias symbol,but then i get warning message and netrev fall down. Please how i can do this? i take pleasure from all kind of advice.
