PSpice Advanced Analysis

Cadence® PSpice® Advanced Analysis is a circuit simulation software which enables engineers to create virtual prototypes of designs and maximize circuit performance automatically. 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 core PSpice simulation, PSpice Advanced Analysis maximizes design performance, yield, cost-effectiveness, and reliability.

Overview

Advanced Analysis helps address the following engineer’s concerns:

  • 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?

Highlights

  • Automatic performance optimization algorithms improve design quality and engineer productivity
  • Find optimum combination of component values; automatically simulate, evaluate results, and adjust component values to reach performance requirements
  • Retarget existing designs with new goals without modifying the layout
  • Go beyond just debugging waveforms—use PSpice AA to help you optimize your design, improve your design reliability and manufacturing yield, and reduce your component selection cost
  • Tight integration with schematic tools for improved accuracy 

Analysis

  • Analog Circuit Optimizer
    Analog Circuit Optimizer

    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 Analog Circuit Optimizer for: 

    • Improving design performance 
    • Updating designs to meet new specifications 
    • Optimizing behavioral models for top-down design and model generation 
    • Saving engineering time by taking over the often "mindless" task of final optimization 
    • Optimizing to a set of goal functions and/or a set of curves
  • Sensitivity Analysis
    Sensitivity Analysis

    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 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.
  • Monte Carlo Analysis
    Monte Carlo Analysis

    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 for:

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

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

    Smoke Analysis :

    • Identify - 
    1. - Components exceeding manufacturers’ limits
    2. - Breakdown voltage across device terminals
    3. - Maximum current limits
    4. - Secondary breakdown limits
    5. - Junction temperatures
    6. - Problem parameters for exceeding limits
    • Calculate Peak, Avg. and RMS power dissipation for each component
      • - Compare these values against corresponding safe operating limits
    • Designs can be derated to meet requirements
  • Parametric Plotter
    Parametric Plotter

    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 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
