PSpice Advanced Analysis Option

Cadence® PSpice® Advanced Analysis Option is a circuit simulation software which enables engineers to create virtual prototypes of designs and maximize circuit performance. It combines Sensitivity, Monte Carlo, Smoke (stress) analysis, Parametric analysis and an Optimizer to provide an expanded environment to take design analysis beyond simulation. Used in conjunction with the core PSpice simulation engine the PSpice® Advanced Analysis Option maximizes design performance, yield, cost-effectiveness and reliability.

Overview

PSpice Advanced Analysis Overview

Advanced Analysis helps address the following engineer’s concerns:

The design might work correctly in the "lab," but can we go to production with it?

• Will it operate correctly -

◦ Over manufacturing tolerance variations?

◦ Outside of temperature range?

◦ Over its full operating range?

◦ With age?

• Are the individual components being over-stressed?

• Will it fail in test or in the field?

• Are there critical sensitivities that will cause problems in the future?

• Which components will most likely fail during manufacturing?

Analysis

Analog Circuit 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.

Use PSpice® Advanced Optimizer Option for:

Improving design performance
Updating designs to meet new specifications
Optimizing behavioral models for top-down design and model generation
Efficient time management on final optimizations.
Optimizing to a set of goal functions and/or a set of curves.

The Sensitivity Analysis identifies which component parameters are critical to the design goals of circuit performance. By analyzing the behavior of components for the entire circuit, it evaluates yield versus cost tradeoffs, thereby maximizing cost-effectiveness.

Use Sensitivity Analysis in PSpice® Advanced Analysis Option for:

Identifying the sensitive components within the circuit, then export the components to Optimizer to fine-tune the circuit behavior.
Estimating worst-case performance of the circuit given the device tolerances.
Identifying which components affect yield the most, then tighten tolerances of sensitive components and loosen tolerances of non-sensitive components.
Enhanced PSpice® Advanced Analysis flow provides the ability to efficiently add global tolerances and distributions.

The Monte Carlo Analysis 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 in PSpice® Advanced Analysis Option for:

Calculating yield based on your specifications
Calculating statistical data
Displaying results in a probability density histogram
Displaying results in a cumulative distribution graph.

The Stress Test Analysis warns of component stress due to power dissipation, increases in junction temperature, secondary breakdowns, or violations of voltage/current limits which over time causes circuit failure. Stress test helps in identifying problems and preventing circuit failure.

Use Smoke Analysis in PSpice® Smoke Option to:

• Identify

- Components exceeding manufacturers’ limits
- Breakdown voltage across device terminals
- Maximum current limits
- Secondary breakdown limits
- Junction temperatures
- Problem parameters for exceeding limits

• Calculate Peak, Avg. and RMS power dissipation for each component

- Compare these values against corresponding safe operating limits

• Evaluate designs for derating requirements

The Parametric Plotter enables sweeping of multiple parameters after creation of circuit simulation and provides analysis of sweep results and feasibility to sweep any number of design and model parameters (in any combination).

Use Parametric Plotter in PSpice® Advanced Analysis Option to:

Sweep component values, model parameters and design parameters
Select sweep-type: Discrete, Log or Linear
Do nested sweeps to explore solution space for multiple measurements
Examine solution space as tabular view and sort the data within already sorted columns
Create and display multiple plots to examine measurements as function of various parameters
View sweep results in tabular or plot form
