Cadence OrCAD 16.5 provided a full set of PCB editing tools to manage and define design intent from logical schematic through physical implementation. The release integrated industry-leading, production-proven, and highly scalable PCB design applications to deliver complete schematic entry, simulation, and place-and-route solutions. With these powerful, intuitive tools that integrated seamlessly across the entire PCB design flow, engineers could quickly move products from conception to final output.

Schematic Editor / Capture

The SPB 16.5 updates refined the "mini-routing" capabilities, allowing for the routing of traces in user-defined grids within a component footprint without affecting the global grid. This was particularly beneficial for Ball Grid Array (BGA) fanouts and high-density interconnect (HDI) designs.

To determine if you need an update, open OrCAD Capture or PCB Editor and navigate to Help > About. You will see a long string of numbers.
