IntroductionIntroduction• SPICE (Simulation Program for Integrated
Circuits Emphasis) is a general purpose analog circuit simulator that is used to verify circuit designs and to predict the circuit behavior.
• PSpice is a PC version of SPICE and HSpice is a version that runs on workstations and larger computers.
• PSpice has analog and digital libraries of standard components (such as NAND, NOR, flip-flops, and other digital gates, op amps, etc) which makes it a useful tool for a wide range of analog and digital applications.

Types of AnalysisTypes of Analysis• Non-linear DC analysis• Non-linear transient analysis• Linear AC Analysis• Noise analysis • Sensitivity analysis • Distortion analysis • Fourier analysis• Monte Carlo Analysis

Circuit ComponentsCircuit Components• Independent and dependent voltage and current sources • Resistors • Capacitors • Inductors • Mutual inductors • Transmission lines • Operational amplifiers • Switches • Diodes • Bipolar transistors • MOS transistors • JFET • MESFET • Digital gates
![Page 6: Pspice Introduction 150914165248 Lva1 App6892](https://reader036.fdocuments.in/reader036/viewer/2022062808/5695cf6f1a28ab9b028e1179/html5/thumbnails/6.jpg)
Terminologies Terminologies • Subcircuit: A subcircuit allows you to define a
collection of elements as a subcircuit (e.g. an operational amplifier) and to insert this description into the overall circuit.
• EDIF: Electronic Design Interchange Format, a standard published by EIA. Usually used for netlists.

File structure PSPICE File structure PSPICE (Capture)(Capture)
• Input file for PSpice that has the file type “.CIR”
• When a circuit is simulated “.OUT” is generated• “*.DAT” file is by default a binary file to see the
data • “*.LIB” files where the details of complex parts
are saved• Additional files
o *.SCH (the schematic data, itself)o *.ALS (alias files)o *.NET (network connection files)
![Page 8: Pspice Introduction 150914165248 Lva1 App6892](https://reader036.fdocuments.in/reader036/viewer/2022062808/5695cf6f1a28ab9b028e1179/html5/thumbnails/8.jpg)
LibrariesLibraries• These are files that contain reusable part data.• They can be custom or default ones• Some of the libraries available in the Evaluation
version of PSPICE are: o abm.slb for special functions like square root and
multipliers o analog.slb for analog components like resistors and
capacitors o breakout.slb for pots o connect.slb, .plb for connectors o eval.slb, .plb for semiconductor, digital devices,
switches o port.slb for grounds, high/low digital ports o special.slb for ammeters, viewpoints o source.slb for various analog and digital sources

PartsParts• Part is a basic building block which may represent
o One or more physical elemento Functiono Simulation modelo When a part is placed for first time its entry is done in “Design Cache”
What is “Design Cache”????... Go and Find Out Yourself

Design StructureDesign Structure• Flat Design
o Small designso All pages in same schematico Off Page connectors are
usedo Figure shows design hierarchy
![Page 11: Pspice Introduction 150914165248 Lva1 App6892](https://reader036.fdocuments.in/reader036/viewer/2022062808/5695cf6f1a28ab9b028e1179/html5/thumbnails/11.jpg)
• Hierarchical Designo Much complex designso Symbols are created called “Hierarchical Blocks”
![Page 12: Pspice Introduction 150914165248 Lva1 App6892](https://reader036.fdocuments.in/reader036/viewer/2022062808/5695cf6f1a28ab9b028e1179/html5/thumbnails/12.jpg)
Things to remember Things to remember before startingbefore starting
• PSpice is not case sensitive • All element names must be unique • There must be a node designated "0" (Zero). This
is the reference node against which all voltages are calculated.
• If any change is made in circuit make sure you create netlist again before simulating it.
![Page 13: Pspice Introduction 150914165248 Lva1 App6892](https://reader036.fdocuments.in/reader036/viewer/2022062808/5695cf6f1a28ab9b028e1179/html5/thumbnails/13.jpg)
Getting StartedGetting Started• File New Project Analog or Mixed A/D
Make sure to choose Analog or Mixed A/D and proper location for project
![Page 14: Pspice Introduction 150914165248 Lva1 App6892](https://reader036.fdocuments.in/reader036/viewer/2022062808/5695cf6f1a28ab9b028e1179/html5/thumbnails/14.jpg)
• Next comes following window
Make sure you select “Create a blank project”
![Page 15: Pspice Introduction 150914165248 Lva1 App6892](https://reader036.fdocuments.in/reader036/viewer/2022062808/5695cf6f1a28ab9b028e1179/html5/thumbnails/15.jpg)
• This is how a typical “Schematic” Window will look like
