I have an existing design that is lacking in a summary sheet or some sort of top level block diagram that identifies nets entering and leaving the schematic or system. I know from working with Cadence there was a feature that would look at all of the sheets in the schematic and create a block diagram that would show the ports entering and leaving the design. Does anyone know if that feature exists in DX designer - we use netlist flow. I am pretty sure it doesn't exist in PADS.
You would have to create this manually and it should be the first step you take to design hierarchically. I will move this discussion to the DxDesigner thread, there you will find four videos on hierarchy.
