This iteration introduced automated interactive routing, allowing designers to speed up the manual trace routing process. The Windows Transition: PADS PowerPCB (1990s–2002)

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

In the late 1980s and early 1990s, PADS-PCB and PADS-2000 operated entirely within the Microsoft DOS environment. These early iterations introduced core concepts still used today, such as the separation of schematic capture and physical layout, basic design rule checking (DRC), and netlist importing.

Operating in the DOS environment, early versions focused on basic footprint creation, netlist importing, and manual interactive routing. It gained popularity for its speed and low hardware requirements compared to mainframe CAD tools.

Transitioned critical engines to 64-bit architecture to handle dense, high-pin-count systems without memory crashes. It fully integrated PADS Designer (formerly DxDesigner) as the primary front-end schematic tool. PADS VX.2 (2016–2018)

PADS 2000s era

: The software gained traction among small-to-medium teams as CAD transitioned from hand-drawn stencils to computer-aided layout. Acquisitions & Shifts : In 2000, Kyoden sold PADS to

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

In 2017, Mentor Graphics was acquired by Siemens, and PADS has since become part of the Siemens EDA (Electronic Design Automation) portfolio.
