PathWave ADS for Layout

Design Editing and Layout

GDSII translators:

  • GDSII importer improves its handling of design elements that are on unmapped layers

General Editing Improvements

  • The shape and size configuration for solder mask and solder paste has been enhanced to support use cases of key customers
  • In 3D layout view, 3D bounding cuboid, instead of edges, of an instance can be drawn via a preference setting
  • Filtering capability has been added to all layer selection combo boxes to allow narrowing down the layers of interest
  • Plane tool has been enhanced to support global net-based clearance constraint hierarchically
  • When routing traces, unconstrained vias are now selectable in the via selection box when constrained vias are also available. The selection combo box presents the sets in logical grouping
  • (Beta feature) the new Simple Evaluator, set as the default evaluator since ADS 2023, has further enhanced to handle bondwire variables and several other use cases the existing Full Evaluator could handle. This evaluator processes component parameter expressions significantly faster than the existing Full Evaluator

Data Display

Data Viewing, Analysis and Manipulation

  • Improved the management and transparency of DDS AEL files being loaded:
    • The new AEL File Manager enables the following:
      • Allows specifying a list of AEL files to be loaded from SITE, INSTALL and workspace locations
      • Added option to reload AEL files without having to restart ADS
    • Added new pre-defined equations for displaying list of DDS AEL files loaded at various locations
    • The Archive/Unarchive Workspace commands have been enhanced to handle DDS AEL files, located either in the workspace or outside, with intuitive user interface to support all likely use cases
  • Enhancements in Expression Manager:
    • New context menu to automatically augment the selection by adding all equations that use the selected equation
    • The Equation Hierarchy dialog, invoked from the Show Hierarchy context menu, has been re-structured into a tree format to also presents all the references to the selected equation

    • New measurement equations are added to measure the third moment and the fourth moment of a statistical distribution: skewness and kurtosis
    • The non-effective statistical variables are now eliminated from the simulation

Electrothermal (ETH) Simulation

  • Dynamic reuse + GUI: generation and use of a reduced-order thermal model 
  • GUI added in ADS 2023 Update 1
  • Enables significant speedups in transient or circuit-envelope electrothermal sims
  • Improve efficiency and accuracy of thermal modeling of complex polygons common in PCBs or modules
  • Parallelized ETH model generation - no new settings are required

Design Rule Check

  • The DRC Create Rules dialog supports a technology layer with the name 'default'

Electrical Rule Check

  • Electrical Rule Check (ERC) Current Density shows the current density at each component pin with highlighting in schematic and layout. To get started using ERC, from the ADS Main window select Open an Example > Training Examples > Layout Verification > Layout Verification Tools Tutorial

Layout Versus Schematic

  • The LVS dialog Auto View supports the checked state (Zoom or Center) and the unchecked state (no update to the window view)
  • The LVS dialog can be configured as a generic LVS viewer. Use the command interface to define mapped/unmapped components, mapped/unmapped nets and parameter mismatches. The viewer supports highlighting in schematic and layout
