Mentor Graphics Pads Version History (2027)

The history of PADS (Personal Automated Design System) is a decades-long journey that mirrors the evolution of the entire electronic design automation (EDA) industry. From its origins as a budget-friendly DOS application to its current status as a sophisticated suite under Siemens, PADS has remained a staple for independent engineers and small-to-medium design teams. 1. The Early Era: PADS-PCB and the DOS Roots (1985–1990s)

5. Siemens EDA Era (2021–Present): PADS Professional+

Following Siemens’ acquisition of Mentor Graphics (completed 2017), the first Siemens‑branded releases arrived in 2021, focusing on cloud collaboration and mechanical‑electrical co‑design.

Why Version History Matters for Users

File compatibility: A board saved in PADS 9.5 cannot be opened directly in PADS 2005. Always check the backward compatibility chart – usually limited to 2–3 major versions.
Library migration: Moving from pre‑VX to VX.2+ requires running the Library Converter tool. Do not skip intermediate releases.
Scripting: VBScript macros from PADS 2007 still run in VX.2, but are deprecated in Professional 3.x (replace with Python API).

The first version of PADS, version 1.0, was released in the early 1980s by PADS, a company founded by three engineers in the United States. The software was initially designed for MS-DOS and provided basic PCB design capabilities, including schematic capture, component placement, and routing. Over the next few years, PADS released several updates, including version 2.0, which introduced support for hierarchical designs and version 3.0, which added capabilities for high-speed design and simulation. mentor graphics pads version history

PADS 2007: Introduced high-speed analysis, RF/microwave circuitry implementation, and early Design for Fabrication (DFF) checking. The PADS 9.x Series

In 2005, Mentor Graphics released PADS Xtreme, a major upgrade that introduced a new architecture and user interface. PADS Xtreme was followed by PADS Plus, which added advanced features such as: File compatibility: A board saved in PADS 9

Mentor Graphics acquired Innoveda in 2001, integrating PADS into its larger electronic design automation (EDA) ecosystem.
