Follow Net

Following a net might take you to another page or another level of design hierarchy in your design. Following nets is useful when your design is split into multiple pages or if it includes some hierarchical logic levels.

For a net that spans across multiple pages or hierarchical boundaries, the Follow Net right click menu option lists all the pages where the net is ON. Click the page number to follow the net. If the number of pages on which the net appears exceeds 24, the page list shows ellipses (~~~) to shorten the list. Pages that are close to the current page are not shown as ellipses. Only pages farthest away (except the first and the last page) from the current page are shown as ellipses.

Double-clicking a net jumps to the next page where the net is on.

Nets that continue on other pages are terminated by a page connector symbol (>). Note that a net can continue on many pages.

??? Indicates the net begins on another page.

If following a net involves crossing design hierarchical boundaries, Netlist Viewer always executes push and pop operations to reach the instance the net is connected to, regardless of whether the Do Selection Locally option is enabled or not.

To follow the net to all the components connected to the net:

  1. 1.Right-click the net to select it.
  2. 2.Choose Follow Net to follow the net to all components and instances connected to the net.
  3. 3.From the sub-menu, choose one of the following:
    • Page x: The component is located on a different page. No hierarchical boundary is crossed. Only this option is available in the Flattened Netlist View.
    • Relative path Instance Name (Upper Level: Pin_name). Need to go up one level of hierarchy
    • Relative Instance Name (Instance Name: Pin_name_). Need to go down one level of hierarchy.
