PSpice
Model Non-Linear Passive Devices with Mathematical Expressions
PSpice now allows modeling of nonlinear behavior for passive devices such as resistors, capacitors, and inductors using mathematical functions. Nonlinear devices are available under the Ideal Devices > Passive Category in the Component Explorer panel.
New Built-in Functions to Model STEP and Random Functions
PSpice A/D now supports the following step, mathematical, and random functions to model the electrical behavior of a circuit:
SMSTP(X)STPA(X)BUF(X)DNLIM(LOWERLIMIT,X,SOFTNESS)HYPOT(X,Y), LENGTH(X,Y)INT(X), TRUNC(X)INV(X)UPLIM(X, UPPERLIMIT,SOFTNESS)URAMP(X)NRAND(X, S)ZRAND(X, S)RANDOM(X, S)ZRANDOM(X, S)ROUND(X)WHITE(X, S)
New Memristor Models
PSpice now supports advanced built-in functions to model memristors. The new models are included in the memristor.olb library.
Support for Automotive Transient Sources CI 210, ISO 16750-2
Transient sources for standard CI 210 have been added, which test AC immunity from continuous disturbances. PSpice now supports the following additional ISO 16750-2 transient sources used for automotive applications for 12V and 24V systems:
- 9.1 Single Line Interruption
- 6.4 Load Dump Without Centralized Load Dump Suppression – Test A
- 6.4 Load Dump With Centralized Load Dump Suppression – Test B
Support for GaN MOSFETs in Component Explorer
GaN MOSFET models are now available and can be accessed from the Component Explorer panel under Discrete.
Sweep Models in Single Simulation Run
PSpice now supports sweeping of components models to perform design exploration with different models in a single simulation run. Evaluate different models for a given base model and compare them to see how the circuit behavior changes for different models.
Support for Expressions with Node Voltages and Current in .MEASURE
The .MEASURE commands can now be used to evaluate complex expressions that include node voltages and current. Additionally, different parameters, including voltage, current, global parameters, and temperature; can be swept.
Cloud Access
OrCAD X PSpice Designer and OrCAD X PSpice Design now have access to OrCAD X Cloud.

The Import Pin Delay feature allows pin delay to be imported from various file formats, such as Excel files, Allegro Constraint compiler files, and existing pin delay formats.
The Auto Define Differential Pairs feature simplifies the process of defining differential pairs in a PCB design, saving time and effort. The functionality is accessible from the top-level menu and supports default differential pair patterns.
The Export Libraries feature extracts libraries from translated third-party designs, making it easier to reuse libraries in OrCAD X Presto designs.
LiveDoc now provides the ability to add assembly notes and instructions as well as using variables in title blocks and assembly notes. The variable values can be defined in the Property panel of LiveDoc and update globally across the document.
This update modernizes the way text is managed in PCB designs, aligning the tool with industry-standard applications. You now have the flexibility to choose from a wide range of fonts that reflect personal or corporate branding while also improving the visual clarity and consistency of design documentation. In addition to standard fonts, the Mooretronics font is also supported within layout editors.
The docked Constraint Manager is a new Constraints panel that simplifies the process of assigning and visualizing constraints directly from the Layout Editor user interface. It presents constraints in a graphical format and organizes them under Basic and Advanced modes. Constraints can be controlled at the group level rather than the net level by assigning constraint sets at the net group, net class, and differential pair levels within the Object Hierarchy panel.
Smart Search is a new search engine that generates predictions based on entered keywords or questions to find the information you need to complete a task directly in the layout. This feature is useful when modifying the design by applying object properties or setting user preferences while working on it.
A new configuration-based solution defines all required data exports and manages export parameters in a single dialog box. It eliminates the need to explore different areas of the layout editor to produce manufacturing exports.
The enhanced pin delay import feature provides auto-detection, column and cell validation, and the ability to adjust column categories and values directly within the dialog box without modifying the source CSV file. The enhanced functionality queries the database to flag missing Reference Designator and Pin Number combinations in the design and allows selective import by deactivating rows and columns as required.
In this release, Cadence continues to expand the capabilities of 3DX Canvas, helping designers visualize their PCB layouts in a highly realistic 3D environment before sending the layouts to manufacturing. 3DX Canvas has been enhanced to selectively display and incrementally add objects to the 3DX Canvas, making the environment far more interactive and efficient. You can now highlight selected objects in the 3DX canvas from the PCB, cross-probe objects, and adjust the 3D view automatically.
OrCAD X PCB Editor has several performance enhancements added included DRCs, import and export of design data, placement and interactive placement, routing and interactive routing, dynamic shapes, padstack refresh, 3D view, and in-design analysis.
Review a schematic design using comments and markups. Mark any area in the design canvas using rectangular or arrow markups and add text comments in for efficient design reviews.
Find objects by parts, pins, nets, text, class, with additional search criteria for object properties and display properties. Efficiently replace values using the new replace dialog box.
The settings of a design template can now be saved as a .dtp file and loaded to reuse in a design. Save and load templates for later reuse in schematic designs allowing you to quickly configure design properties such as text font and size.
Share workspaces directly via the Web, making collaboration with team members and stakeholders easier. This feature enables seamless sharing of design data, eliminating the need for manual file transfers and ensuring that everyone has access to the latest design information.
