MODEL LIBRARY
• Select from more than 20,000 analog and mixed-signal models of industry devices
• More than 4,500 parameterized models for BJTs, JFETs, MOSFETs, IGBTs, SCRs, magnetic cores
and toroids, power diodes and bridges, operational amplifiers, optocouplers, regulators, PWM
controllers, Multipliers, timers, and sample-and-holds. These models allow passing simulation
parameters as properties from the Schematic Editor
• Access basic components plus a variety of macro-models for more complex devices, including
operational amplifiers, comparators, regulators, optocouplers, ADCs, and DACs
• Use state space average models to do fast feasibility simulations and control loop analysis for
Switched mode power supplies
SYMBOLS FROM MODELS:
• Automatically generate OrCAD Capture parts for the models created by the Model Editor
• Automatically generate OrCAD Capture part libraries from simulation model libraries obtained
from part vendors or colleagues
• Base the symbol generation on the PSpice symbol set, or your own
• Generate symbols for analog, digital, or mixed-signal devices (both primitives and macro-models)
PSPICE MODEL EDITOR
• Accessible from a part in OrCAD Capture, the intuitive user interface of the PSpice Model Editor
can be used to view or edit its simulation model
• Encrypt model data to protect IP
• Add tolerance, distributions and maximum operating conditions (stress data) besides simulation
data to the model for advanced analysis
• Extract a model of a supported device type by simply entering required data from the device
datasheet
• Proceed quickly through the extraction process using fully interactive features as a guide. Device
characteristic curves give you quick graphical feedback
BEHAVIORAL MODELING
• Describe functional blocks using mathematical expressions and functions
• Leverage a full set of mathematical operators, nonlinear functions, and filters
• Implement any transfer function via controlled voltage and current sources
• Define circuit behavior in the time or frequency domain, by formula (including Laplace trans-
forms), or by look-up tables
• Select parameters which have been passed to sub-circuits in a hierarchy and insert them into
transfer functions
• Create Boolean expressions that reference internal states and pin-to-pin delays using digital
behavioral modeling
