Net is not getting highlighted

AP202601223013

Hi,

I have prepared a schematic which consists of Power supply section which is a rectifier section and named the negative side of the rectifier by selecting a Ground from the design cache. Then I connected the Ground with a hierarchical port to extend the schematic to the next page which is an Inverter section. Here, after the schematic completion, when I click on signals options by right clicking the Ground net at the rectifier section section, it is getting highlighted (Ground signal) at the rectifier section. But at the inverter section next page, it is not getting highlighted. I checked the properties of the net at the inverter section which is a hierarchical port named as Ground. In the properties, I got two options under the Nets section namely, GND and VSS (VSS is another net for signal Ground). I changed the Net name to Ground. But still it is not getting highlighted. Why is this?

    In OrCAD Capture, global signals, like GND or VCC, are used throughout the design. Issues arise when you attempt to connect off-page connectors or h-port directly to these global power symbols, which might result in unexpected net naming, net localization, or broken connectivity.

    To properly connect a power symbol like GND in the entire design (across pages and blocks), off-page connectors or H-ports are not needed. You can use just the power symbol like the following:

    1. Place the power symbol (GND/VCC) on each page where needed. The power signal, being global, is automatically connected across the pages in the entire design. So, all GND symbols in the design (on different pages and blocks) will be shorted to each other without needing an off-page connector or H-port. 

    2. Place the power symbol on a page of the root schematic. Say, you placed a GND power symbol in the root schematic. Now, to place the GND signal on any page in the design, you just need to assign the alias GND to a net. It gets connected to the GND global signal in the design.

    In the above two scenarios, an off-page connector or H-port is not needed to transfer the GND signal's connectivity from one page to another.

    Hope it clarifies!
