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

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

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

6. Main Menus, Tools and Modules Analysis Menu Wiring Tool Parts Library Simulate Markers Bias Display 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
