The Graphical Diff Platform for Schematics and Layouts

 The Graphical Diff Platform for Schematics and Layouts

Simplify and enhance graphical diff with Keysight Visual Design Diff (VDD)

 Compare Schematics and Layouts

Keysight VDD enables designers to quickly compare different versions of a schematic or layout by graphically highlighting the variations in the design editor. Analog designers use VDD to identify and review design schematic and layout modifications and debug design regressions and ECO flows.

Cadence Virtuoso Integration

Keysight VDD works with the Cadence Virtuoso platform to detect modifications to nets, instances, layers, labels, and properties. VDD highlights all differences between two versions of the same cell view or between any two cell views of the same type. Supported view types include schematics and layouts.

Hierarchical Diff Checks

With Keysight VDD gives designers the option to check for differences hierarchically. The platform can flag all differences for the entire design hierarchy below the selected view. Design teams can also automate ECOs by running Keysight VDD in batch mode and exporting differences to a text or CSV format.

Problems Keysight VDD Can Solve

-Identifying changes in schematics and layouts is difficult and time-consuming.

-Schematic and layout designers and engineers often struggle to communicate effectively.

-Failing to report, visualize, and review all changes during engineering change order (ECO) meetings leads to oversights.

How Keysight VDD Can Help

Keep schematics and layouts in sync: Keysight VDD keeps all schematics and layouts remain100% in sync. This enables easier collaboration between layout engineers and schematics. Schematic engineers can amend schematics without having to transfer notes to layout engineers. It is possible to view all updates and modify layouts to match them.

Review changes before checkins: Keysight VDD allows you to review changes before checkins using automated and accurate reports. VDD outlines all changes — even cosmetic — between new and old schematics and layouts. In addition, you can hide cosmetic changes from view.

Streamline engineering change order (ECO) design reviews: Keysight VDD makes it easy to prepare for ECO reviews. The platform automatically generates reports outlining all changes for easy and reliable reporting.
