Mentor Graphics — Pads Version History //top\\

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)

Version 2.0 – 3.0 (1997–1999)

Mentor Graphics acquired Innoveda in 2001, bringing PADS into its extensive portfolio of design tools. PADS 2005 / 2007: During the mid-2000s, Mentor released versions like mentor graphics pads version history

  • 1. Introduction

    1990s

    : Expanded capabilities by acquiring HyperLynx (1997) for signal integrity and ACT (1998). The history of PADS (Personal Automated Design System)

    : Added features for RF design, such as via matrixing and DXF-in import. It also improved high-speed routing and introduced Design for Fabrication (DFF) analysis. PADS 9.x (approx. 2009–2013) File compatibility: A board saved in PADS 9

    • 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).
