Unlike some open-source EDA tools that can crash when handling complex routing, OrCAD 16.6 is built on a mature, stable codebase. It handles library management and schematic entry with a level of reliability that inspires confidence.
For automatic routing, the Lite version includes the Specctra-based PCB Router, though saving the results of a routing session is disabled. Right-click setup
Added bi-directional STEP model support, allowing you to verify designs within mechanical enclosures.
To encourage upgrading to professional versions, OrCAD 16.6 Lite had strict "glass ceilings" on design complexity: It handles library management and schematic entry with
Access a vast library of parts for schematic drafting.
At least 5 GB of free hard drive space (SSD preferred).
