August 10, 2020

Duration: 15 Minutes | Version Required: 17.4

There are only so many hours to your workday, limited designers, and stricter schedules. It is more important than ever to speed up your design process where you can. Routing dense, complex boards is a time-consuming process; however, with the interactive routing capabilities available in OrCAD, routing no longer takes a significant time investment. OrCAD interactive routing capabilities provide engineers the advantage they need to complete routing with intelligent, guided automation.

This document is intended to provide step by step instructions on how to utilize interactive routing in OrCAD PCB Designer Professional. For this workshop, download the design files and use the provided design, InteractiveRouting_Start.BRD, to follow along. To view the completed design, select InteractiveRouting_Finish.BRD.
