Tech Tip: Design Force Daisy Chain Topology Template


CR-8000 Design Force has the ability to assign Topology Templates to E-nets in the Constraint Browser. Topologies such as Daisy Chain, H-Tree, Star, Remote Star, or Custom can be assigned to E-nets to be sure the high-speed nets are routed correctly. By using these Topology Templates, you can control the way the nets are routed.

When routing high-speed nets, the topology, (the way, and order they are routed) becomes very important. When routing a Daisy Chain topology, you can control the pin connection order by assigning a Topology Template and setting the order of the connecting Nodes. Once you assign the Topology Template the routing guides and Virtual Branch Points will show the correct routing order. You can also assign track width rules between pins, or virtual branch points.

Assigning Topology Templates in CR-8000 Design Force can ensure your design is routed as designed.

The following video will demonstrate a Daisy Chain Topology Template.
