When advanced technologies are utilized in a design, more sophisticated rules and constraints are needed. Some constraints may be more physical, such as traces and nets that must be routed on a specific layer, or need to be restricted to a certain area of the board. These may be easy to keep track of manually for a few nets, but if you have hundreds, even thousands of complex constraints, you need an automatic way to manage and adhere to these during design.
RF Laboratories, Inc. discusses how PADS Professional Constraint Management drives their designs. This is a short video of RF Laboratories Inc. David Zima’s webinar presentation in April 2020.
