The history of PADS begins not with Mentor Graphics, but with PADS Software, Inc., founded in 1986. The original product, known simply as PADS-PC, was a DOS-based application.

During this era, the software gained a reputation for having a highly efficient router and a user-friendly interface that relied heavily on keyboard macros (many of which are still supported in the software today as "Modeless Commands").

Below is a concise, chronological summary of notable PADS releases, major features, and platform changes from Mentor Graphics (now part of Siemens EDA). This is a high-level overview — for detailed patch notes or build numbers, consult official release documentation.

If you want a complete, version-by-version changelog or links to specific release notes (build numbers, exact dates, bug fixes), say which product variant and time range you need (e.g., "PADS Professional 9.5–2022"), and I will fetch more precise details.

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)

PADS was originally created by Gene Marsh and his son in the mid-1980s.

1985 Release: The first version, PADS-PCB, debuted for DOS. At just $495 per seat, it democratized PCB design, which was previously locked behind expensive, proprietary Unix workstations.

Market Growth: Headquartered in Marlborough, MA, the company grew rapidly, becoming a primary competitor to early leaders like PCAD and Calay Systems.

2. Corporate Transitions: Innoveda and Acquisition (1990s–2002)

The late 90s saw PADS bolster its technical capabilities through strategic acquisitions before undergoing significant corporate changes.

Expansion (1997–1998): PADS acquired HyperLynx in 1997, integrating what would become the industry-standard tool for signal integrity. In 1998, they added ACT (Advanced CAM Technologies) to improve manufacturing output.

Ownership Shifts: In 2000, the company was sold to Innoveda, a joint venture involving ViewLogic. This period is often remembered by longtime users for a perceived stall in product innovation. 3. The Mentor Graphics Era (2002–2017)

In 2002, Mentor Graphics acquired Innoveda for $160 million, officially bringing PADS into its portfolio.

PADS 2005 & 2007: Mentor introduced "Flow" bundles, integrating Logic, Layout, and Router into a cohesive Windows-based environment.

The "9.x" Series: Versions like PADS 9.3 and 9.5 were major milestones, widely used for years. These versions solidified the classic workflow of using PADS Logic for schematics and PADS Layout for the board.

PADS Professional (2015): To compete with high-end tools like Altium, Mentor launched PADS Professional. This was a radical shift, as it was built on the high-end Xpedition technology rather than the legacy PADS code. 4. Siemens and the VX Series (2017–Present)

Following Siemens' $4.5 billion acquisition of Mentor Graphics in 2017, the software was rebranded under Siemens EDA. History of PADS - PCB Libraries Forum

PADS (Printed Automated Design System) has evolved from a simple DOS-based tool into a sophisticated suite of electronic design automation (EDA) software. Now part of Siemens EDA (formerly Mentor Graphics), its version history reflects the shift from manual board layout to high-speed, multi-layer, and AI-driven design. The Early Era: 1985–1997

Originally created by Gene Marsh, PADS launched in 1985 as a DOS-based software priced at $495 per seat. With the VX (Variable X) branding, Mentor introduced

PADS-PCB (1985–1990s): Early versions focused on basic 2D layout for double-sided or 4-layer boards.

Transition to Windows: As operating systems evolved, PADS moved away from its DOS roots to support the graphical user interfaces of Windows, becoming a staple for small design bureaus. Acquisition and the Innoveda Years: 1997–2001

This period was marked by rapid corporate shifts and significant technology acquisitions.

1997–1998: PADS acquired HyperLynx for signal integrity and ACT for simulation.

2000: The company was sold to Innoveda, a joint venture between Kyoden and Viewlogic.

PADS 5.0 (1998): This version consolidated many of the newly acquired tools into a more cohesive layout and routing environment. The Mentor Graphics Era: 2001–2017

Mentor Graphics acquired Innoveda in 2001, bringing PADS into one of the "big three" EDA portfolios.
