Focuses on cloud integration, PartQuest partnership, collaborative design review, and DFM improvements. Conclusion
The history of PADS begins not with Mentor Graphics, but with , founded in 1986. The original product, known simply as PADS-PC , was a DOS-based application. mentor graphics pads version history
PADS Pro now acts as a seamless gateway into the broader Siemens ecosystem, allowing PCB designers to easily export exact digital twins of their hardware to mechanical software (NX, Solid Edge) and PLM systems (Teamcenter). Summary of Major Milestones Era / Version Name Approximate Years Operating System Key Defining Feature PADS-PCB / 2000 1980s – Mid 1990s Brought professional PCB layout to the desktop PC.

| | 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) | First 64‑bit file I/O support. |
Mentor Graphics changed the versioning nomenclature to "VX" (Visual Experience) to denote a major architectural update in the graphics engine.
