Mentor Graphics Pads Version History |best|

: 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.

: PADS was first released by Gene Marsh and his son as a DOS-based operating system tool, originally priced at approximately $495 per seat.

By following the evolution of Mentor Graphics PADS through its version history, designers and engineers can gain a deeper understanding of the software's capabilities and limitations, ultimately enabling them to create more effective and efficient designs. mentor graphics pads version history

| | Cons | |---------------------------------------------------|---------------------------------------------------| | Long file backward compatibility (PADS 9.x files open in VX/Pro) | Steep price increase after Siemens acquisition | | Scalable – from simple 2-layer to complex 20+ layer boards | Feature fragmentation across Standard/Plus/Pro | | Strong router (PADS Router / Allegro-like in Pro) | Some versions (VX.0–VX.1) had stability issues | | Excellent simulation integration (HyperLynx) | Documentation can be scattered across versions | | Still used by many contract manufacturers (CMs) | No native macOS/Linux version (Windows only) |

Released in the early 1990s, this version broke the traditional 16-bit memory barriers of DOS. It introduced advanced database capabilities, letting designers handle larger component counts and tighter grid spacing.

The history of PADS (Printed Automated Design System) is a decades-long journey of evolution from a simple DOS tool to a high-end professional EDA (Electronic Design Automation) platform under Siemens EDA Early Origins and Independence (1985–2000) By following the evolution of Mentor Graphics PADS

release platform. This was a major shift that split PADS into three distinct tiers: PADS Standard: For basic PCB design. PADS Standard Plus: Added advanced analysis like HyperLynx. PADS Professional: Powered by Mentor's high-end technology, intended for complex hardware designs. Siemens Acquisition and Modern Era (2017–Present)

Signal Integrity (SI) and Power Integrity (PI) analysis via HyperLynx became tightly integrated into the PADS Professional workflow. PADS VX.2 (2016–2018)

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.
