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.

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.
