Allegro PSpice Simulator

Ensuring Reliable and Optimal Analog adn mixted signal PCB Designs

Finding problems early with accurate simulations before fabrication saves time and budget. Cadence analog/mixed-signal (AMS) simulators enable accurate modeling, verification, and optimization of designs to reduce risk

Cadence® Allegro® PSpice Simulator contains PSpice® technology at its core to provide fast and accurate simulations for analog and mixed-signal designs. This Advanced Analysis package includes utilities for sensitivity analysis, goal-based multi-parameter optimization, component stress and reliability analysis, and Monte Carlo analysis for yield estimation. Allegro PSpice Simulator is a unified environment for taking designs further—improving time-to-market performance and the overall quality of your design while keeping operating costs in check.
When combined with Allegro Design Entry HDL, the schematics drawn in PSpice Simulator can also drive PCB layout, significantly reducing design time and eliminating redrawing errors. It fully explores the relationships in your design with "what if" scenarios before committing to final implementation. PSpice Simulation includes a large library of known models and behavioral modeling techniques that make refining the analog/digital interface a straightforward task.

Analog and Event-Driven Digital Simulationse

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. Digital functions support 5 logic levels and 64 strengths, load-dependent delays, and hazard/race checking. Allegro PSpice Simulator and PSpice® simulation also feature propagation modeling for digital gates and constraint checking (such as setup and hold timing).
Includes a library of more than 30,000 analog and mixed-signal models of devices made in North America, Japan, and Europe.
Also included are more than 4,500 parametrized 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.

Advanced Simulation Capabilities

The Probe feature is a powerful and easy to use tool that helps designers to organize, visualize and utilize their simulation data.
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. The tools also enable users to measure performance characteristics of a circuit using built-in measurement functions and creation of custom measurements. For data display, additional capabilities allow plotting of both real and complex functions of circuit voltage, current, and power consumption, including Bodé plots for gain and phase margin and derivatives for small-signal characteristics

Analog Circuit Optimizer

The optimizer analyzes analog circuits and systems, fine-tuning designs faster than trial-and-error bench testing. It helps find the best component... values to meet performance goals and constraints. Designers can use the optimizer to improve design performance, update designs to meet new specifications, optimize behavioral models for top-down design and model generation, and tune a circuit to match known results in the form of measurements or curves. The optimizer includes four engines: least squares quadratic (LSQ), modified LSQ, random, and discrete.

Sensitivity Analysis

The Sensitivity Analysis identifies which component parameters are critical to the goals of a circuit’s performance by examining how each component affects circuit behavior by itself and in comparison to the other components. It allows designers to identify sensitive components and export them to the optimizer to fine-tune circuit behavior. Using this form of analysis designers can make critical tradeoffs to achieve design goals such as performance, stability and cost.

Monte Carlo Analysis

Monte Carlo predicts the behavior of a circuit statistically when part values are varied within their tolerance range.
Monte Carlo also calculates yield, which can be used for mass manufacturing predictions. Use Monte Carlo for calculating yield based on your specifications calculating statistical data, displaying results in a probability density histogram, and displaying results in a cumulative distribution graph. Define values and objects with perfect syntax.

Smoke Analysis

The Smoke analysis warns of stressed components due to power dissipation, increases in junction temperature, secondary breakdowns, or violations of voltage/current limits.
Over time, these components can cause circuit failure. Designers can use Smoke to compare circuit simulation results to a component’s safe operating limits. If limits are exceeded, Smoke identifies the problem parameters. It can also be used for creating, modifying, and configuring derate files for use with Smoke analysis.

Parametric Plotter

Once a circuit is created and simulated, the parametric plotter is used for sweeping multiple parameters.
Any number of design and model parameters (in any combination) can be swept and results viewed in tabular or plot form. Designers can use the parametric plotter for allowing device/model parameters to be swept, displaying sweep results in spreadsheet format, allotting measurement results in probe UI, and evaluating post-analysis measurement.
