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.
