Yes, by using the Mark Net command, which was introduced in IC 4.4.5. It lets you visually trace a net in
a layout design without having to use a schematic. It extracts the metal and via layer information from the
technology file and highlights the net across multiple layers and hierarchy.
To use the Mark Net command, follow these steps:
1. From the design window, choose Connectivity – Mark Net.
2. Click on a net.
The entire net will be highlighted.
Pressing the Esc key ends Mark Net and removes the highlight from the layout. The Mark Net command
requires that the technology file have a layer connections definition similar to the following. (Im Hit-Kit
sind diese Layer bereits definiert.)

The prop.xx is the file containing library, cell, or view properties. The data inside the prop.xx file provides
functionality to the cellview.
