Definition
Xpedition is a printed circuit board design and layout software suite from Siemens EDA used to create the schematic and physical layout of electronic circuit boards, from component placement through multi-layer routing. It covers the full PCB design flow for complex, high-density boards found in aerospace, automotive, telecommunications, and other industries where a board must integrate large numbers of high-speed signals and components reliably.
Overview
Designing a printed circuit board for anything beyond a simple hobby project requires more than placing components and drawing wires: engineers must manage signal integrity at high frequencies, thermal behavior, manufacturing constraints, and constraints imposed by regulatory or reliability standards, all while coordinating a schematic that may involve thousands of components. Xpedition, originally developed by Mentor Graphics and continued under Siemens EDA following that acquisition, was built to handle this complexity for large, professional PCB design teams. Mechanically, Xpedition provides a schematic capture environment where engineers define a circuit's logical connections and component choices, then a layout environment where those components are placed on a physical board outline and connected through copper traces across multiple layers. The tool enforces design rules and constraints throughout this process—minimum trace spacing, differential pair routing for high-speed signals, and thermal or mechanical keep-out zones—and integrates simulation capabilities to check signal integrity and power distribution before a board design is finalized for manufacturing. Its data management features also let multiple engineers work on different sections of the same large board design concurrently without overwriting each other's changes. Within the PCB design tool landscape, Xpedition sits at the high end alongside Cadence's Allegro, targeting large engineering teams working on complex, multi-board or high-layer-count designs, whereas tools like Altium Designer and the open-source KiCad serve a broader range of users from professional teams to hobbyists with somewhat less emphasis on massive team-based collaboration workflows. Xpedition's strength lies particularly in managing very large, constraint-heavy designs and integrating with other Siemens EDA tools such as Calibre for verification. In practice, Xpedition is used by organizations designing boards for aerospace, defense, automotive, and telecommunications equipment, where reliability requirements and design complexity justify its cost and steeper learning curve relative to more accessible tools. These organizations often need to track component provenance and manufacturing compliance across the board's entire lifecycle, a workflow Xpedition supports more directly than tools built primarily for smaller-scale projects, including managing approved vendor lists and revision history across long-running programs that can span many years from initial design to end of production, a lifecycle scope that far exceeds the needs of a typical short-lived consumer product design. Smaller teams or individual engineers more often reach for Altium Designer or KiCad, reserving Xpedition-class tools for projects where team-based collaboration on very large, highly constrained board designs is the deciding factor, since the licensing and training investment required to use Xpedition well only pays off at that scale.
