Chapter 6
Software for Electronics
Introduction
• This chapter covers the following topics:• Software for electricity and electronics• Multisim• Circuit Wizard• Productivity software for electronics
Software for Electricity and Electronics
• Electronic circuit simulation software :• Models circuit performance• Vital resource to check proper operation• Uses mathematical algorithms to duplicate
circuit operation• Advantageous when breadboarding not
practical or too costly
Software for Electricity and Electronics (cont’d.)
• Berkeley SPICE– Most well-known analog simulator– Industry standard technology
• Best-known digital simulators– Based on Verilog hardware description
language
Software for Electricity and Electronics (cont’d.)
• Mixed-mode simulators– Can simulate both analog and event-driven
digital• Autorouting
– Technique for saving time and money in PCB design
– Results not always satisfactory
Software for Electricity and Electronics (cont’d.)
• Autoplace:• Automatic placement of components on a
PCB• Confirms parts will fit on the board• Autoroute can confirm the component
placement can be routed
Software for Electricity and Electronics (cont’d.)
• Input/output buffer information specification (IBIS) model
• Used in place of SPICE for high-speed circuits
• Provide product information to potential customers:– Without revealing intellectual property
Multisim• National Instruments Multisim :• Electronic schematic capture and
simulation program• Part of a suite of design programs• Uses Berkeley SPICE• Can import and export to board layout
software Ultiboard• Widely used in education and industry

Multisim (cont’d.)
• Virtual instruments available in Multisim• Analog and digital multimeters• Bode plotter• Logic analyzer• Oscilloscope• Signal generator• Wattmeter
Multisim (cont’d.)
• Multisim provides tools to analyze circuit behavior
• National Instruments LabVIEW– Measurement software– Graphical programming environment for
creating instrumentation
Circuit Wizard• New Wave Concepts’ Circuit Wizard• Integrated software• Combines schematic circuit design,
simulation, PCB design, and CAD/CAM manufacture
• Provides tools necessary to produce project
• Includes on-screen testing

Circuit Wizard (cont’d.)
• Select components from a library– Over 1500 simulated components available– Ideal and real-world models for each
• Connect using intelligent wiring tool• Press play button to start simulation• Simulation engine based on Berkeley
SPICE

Circuit Wizard (cont’d.)• Circuit Wizard PCB fabrication features :• PCB components• Designing PCBs• Automatic routing• PCB style views• SPICE PCB simulation• PCB virtual instruments• Links with other CAD packages
Circuit Wizard (cont’d.)
• Circuit Wizard PCB fabrication features (cont’d.) :
• Computer-aided manufacturing (CAM) support
• Bill of materials spreadsheet creation
Productivity Software For Electronics
• Word processing• Presentation• Publishing• Spreadsheet• Many free productivity programs available
on the Internet– Be cautious of viruses
Productivity Software For Electronics (cont’d.)
• Word processing software• Used to enter and edit text, graphics, clip
art, and photos• Examples: Microsoft’s Word and Apple’s
Notes
Productivity Software For Electronics (cont’d.)
• Productivity software• Includes editor and method for displaying
slide shows• Examples: Microsoft’s PowerPoint and
Apple’s Keynote
Productivity Software For Electronics (cont’d.)
• Desktop publishing software types– Word processor– Page layout– Graphic images– Web design
• Design elements– Alignment, contrast, proximity, and repetition
Productivity Software For Electronics (cont’d.)
• Web design– Uses Hypertext Markup Language (HTML)
• Graphical HTML editors– Examples: Microsoft FrontPage and Adobe
Dreamweaver
Productivity Software For Electronics (cont’d.)
• Spreadsheet :• Input and manipulate numerical data• Data placed into cells in a grid• Cells can hold numbers, formulas, or text• Multiple worksheets can exist in a
spreadsheet file
