This module provides a brief introduction to generating schematic reports and annotation in National Instruments Multisim. Multisim is fully featured SPICE schematic capture and simulation tool used for circuit design, simulation, and in combination with Ultiboard for layout of custom PCBs.

Schematic reports and annotation

Multisim allows you to generate a number of reports: Bill of Materials (BOM), Component Detail Report, NetlistReport, Schematic Statistics, Spare Gates and the Cross Reference Report. A BOM lists the components used in your design andtherefore provides a summary of the components needed to manufacture the circuit board. Information provided in the Bills ofMaterials include:

  • quantity of each component needed.
  • description, including the type of part (example: resistor) and value (example: 5.1 kohm).
  • Reference Designator of each component.
  • package or footprint of each component.

The Component Detail Report shows all information stored in the Multisim database for a particularcomponent.

The Netlist Report provides the following circuit connectivity information for each component:

  • Net name.
  • Page (filename).
  • Pin (logical pin name).

The Cross Reference Report provides a detailed list of all components and their locations in thedesign.

The Schematic Statistics Report provides the quantity of the following in a circuit:

  • Components—total number of components. (Real components + virtual components).
  • Real components—components that can be purchased.
  • Virtual components—components that cannot be purchased.
  • Gates—total number of gates used in the design.
  • Nets—total number of connections between pins.
  • Pins in nets.
  • Unconnected pins.
  • Total pins—pins in nets and unconnected pins.
  • Pages.
  • Hierarchical blocks—total number of hierarchical blocks, unique or otherwise. Instances of hierarchical blocks equals thenumber of copies of the same hierarchical block.
  • Unique hierarchical blocks—total number of unique hierarchical blocks.
  • Subcircuits—total number of subcircuits, unique or otherwise.
  • Unique subcircuits.

The Spare Gates Report lists unused gates on multi-section components. Note: Multisim provides a gate optimizerwhich will automatically and efficiently pack multisection parts onto the minimum number of chips. To run the gate optimizer selectTools/Rename/Renumber Components and then select Gate Optimizer.

Graphical annotation

Multisim provides an easy method for graphically annotating your circuits. The Graphic Annotationtoolbar allows placement of the following items: text, lines, multilines, rectangles, ellipses, arcs, polygons, pictures, andcomments. To place graphical elements without using the toolbar, right-click on the schematic and select Place Graphic.

Graphical Annotation Toolbar

Circuit description box

In addition to adding text to a particular portion of a circuit, you can add general descriptions to yourcircuit using the Circuit Description Box. You can also place bitmaps, sound and video in the Circuit Description Box.

The contents of the Circuit Description Box are viewed in the top pane of the Circuit Description Box window(select View/Circuit Description Box). To edit the contents of the Circuit Description Box, select Tools/Description BoxEditor.

Title blocks

A powerful title block editor allows you to create customized title blocks. If desired, a title block can beincluded on every page of your design.

Various fields in the title block are automatically filled in depending upon the context and variousdocument properties. When designing the title block, you choose one of the pre-defined fields or a custom field. You choose appropriatefonts depending upon your language of preference. To edit an existing, or to create a new title block, select Tools/Title BlockEditor.

Title blocks can include elements such as text, lines, arcs, Bezier curves, rectangles, ovals, arcs, bitmaps,and so on.

To place a title block, select Place/Title Block. The title block can be automatically placed in any corner byright-clicking on the title block and selecting Move To. To populate fields of each title block, simply double-click the titleblock.

Schematic transfer to ultiboard and other packages

Multisim includes a single-click feature which will transfer the current design to an installed copy ofUltiboard. Select Transfer/Transfer to Ultiboardto initiate the PCB design process. Designs can be easily forward and back-annotatedusing the same Transfer menu.

In addition to a transfer mechanism between Multisim and Ultiboard, designers also have the option to transferdesigns to one of several other PCB layout packages. Note: Transferring designs to 3rd party layout packages may requirematching Multisim components to components in the database of the chosen PCB layout program.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
how did you get the value of 2000N.What calculations are needed to arrive at it
