Cadence® PSpice® A/D is a full-featured analog simulator with support for digital
elements to help solve virtually any design challenge—from high-frequency systems to
low-power IC designs. The powerful simulation engine integrates easily with Cadence
PCB schematic entry solutions, improving time to market and keeping operating costs
in check. An interactive, easy-to-use graphical user interface provides complete control
over the design process. Availability of resources such as models from many vendors,
built-in mathematical functions, and behavioral modeling techniques make for an
efficient design process.
The 16.5 library has a range of new models that can be used in diverse applications.

The 16.5 release comes with the productivity enhancing feature of partial design simulation. Identify individual components of any design, and, using the partial design simulation feature, simulate only selected portions. Using this feature, you can simulate different circuits in the design with different simulation profiles. In addition, you can compare and merge portions of a design quickly.

PSpice A/D integrates seamlessly with the Cadence front-to-back PCB design flow, making it possible
to have a single, unified design environment for both simulation and PCB design. Select from a library
of more than 18,000 symbols and models for simulation to design with Cadence PCB schematic design
entry technology.
Access built-in functions that can be described parametrically or draw piece-wise linear (PWL) signals
freehand with the mouse to create any shape stimulus. Create digital stimuli for signals, clocks, and
buses; click-and-drag to introduce and move transitions.
Users can easily set up and run simulations, and then cross-probe simulation results from Probe,
an industry-standard waveform viewer. Support for multiple simulation profiles enables users to recall
and run different simulations on the same schematic.
Integrated analog and event-driven digital simulations improve speed without loss of accuracy. A single
graphical waveform analyzer displays mixed analog and digital simulation results on the same time axis.
Probe Windows allows users to choose from an expanded set of mathematical functions to apply to
simulation output variables. Designers can create plot window templates and use them to easily make
complex measurements by simply placing markers directly on the desired pins, nets, and parts in the
schematic.
Included are a large variety of accurate internal models—which typically include temperature effects—
that add flexibility to simulations. Models are available with R, L, C, and bipolar transistors plus: built-in
IGBTs; Seven MOSFET models;five GaAsFET models; nonlinear magnetic models; transmission line
models; digital primitives; and two battery models.
Users can select from more than 18,000 analog and mixed-signal models of devices made in North
America, Japan, and Europe. Also included are 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.
Functional blocks are described using mathematical expressions and functions, which allows
designers to leverage a full set of mathematical operators, nonlinear functions, and filters. Circuit
behavior can be defined in the time or frequency domain, by formula (including Laplace transforms),
or by look-up tables.
The Magnetic Parts Editor helps designers overcome issues involved in manually designing
transformers. Users can design magnetic transformers and DC inductors, and generate simulation
models for trans-formers and inductors.
This feature allows designer to store simulation states at various time-points and then restart
simulations from any of the simulation states, which saves time. The designer can modify simulation
settings and design parameters before starting a simulation from a pre-recorded time-state.
This option makes the simulator automatically change tolerances limits of convergence to make the
design converge. Designers can use this option to achieve convergence and then fine-tune
simulations by further modifying simulator options.
Using optional PSpice Advanced Analysis capabilities, designers can automatically maximize the
performance of circuits. Four important capabilities—sensitivity analysis, optimization, Smoke (stress
analysis), and Monte Carlo (yield analysis)—enable engineers to create virtual prototypes of designs
and maximize circuit performance automatically.
Customers with proper training will receive a much greater return on their investments. Even a seemingly small productivity improvement can have a significant effect on time-to-market, and can have a noticeable effect on your bottom line.
