  1. Introduction to PSpice R. E. Abdel-Aal February 2005

  2. Outline • What is PSpice? • Types of Analysis • Main Menus, Tools and Modules • Steps of Performing Analysis • A Guided Tour

  3. What is PSpice? • PC version of the older SPICE software (Simulation Program with Integrated Circuit Emphasis) • SPICE has been the standard method of device-level IC circuit simulation since the early 1970s • Performs nonlinear dc, nonlinear transient, and linear ac circuit solutions. Also temperature analysis and noise analysis. • Other circuit simulation software include:MultiSim7, nVisage, TINA Pro, Micro-Cap 8, ICAP/4.

  4. Types of Analysis Available Basic Single-Run Analyses: • DC Bias Point Details • DC Sweep: e.g for Transfer Function • AC Sweep and Noise: e.g. for Frequency Response • Transient and Fourier: Time Domain Analysis

  5. Types of Analysis Available Advanced Multi-run Analyses: • Systematic: Parametric and Temperature • Statistical: - Monte Carlo Randomly varies all parameters having a tolerance - Sensitivity/Worst Case

  6. Analysis Menu Wiring Tool Parts Library Simulate Markers Bias Display Main Menus, Tools and Modules Schematic Capture Window in PSpice V.8

  7. Parts Library • Circuits Elements: • - R, L, C • - Diodes, Transistors • - Digital, Analog ICs • Sources: • - DC, AC, Pulse, PWL • - Voltage, Current • - Grounds • Probes, etc: • - Viewpoint, Iprobe

  8. Analysis Setup

  9. The Probe • Multi-trace • plots versus time, • frequency, voltage, temperature, etc. • Two independent • Cursors • Trace data can be • exported to Excel • Trace function can be user-defined

  10. The Probe: Trace Functions

  11. Steps of Performing Analysis • 1. Prepare the schematic: • Get and place parts • Set values and attributes • Wire-up the circuit (Remember grounding) • Save into a file • 2. Simulate and Debug 3. Analyze

  12. Guided Tour and some examples
