We could also have done this by individually editing the parts and checking the exclude from

Active Variant box on the Edit component dialogue. You need to be very careful when working

this way to ensure that you have first selected the variant you want from the combo-box at the

top.

Finally, you can quickly manage variants for a group of parts by first dragging a selection box

around the parts and then showing selected in the search tab of the design explorer.

The Proteus software manages the variant information through all of the output systems,

changing the BOM Report, the Pick and Place files, the Assembly Drawings, the 3D Viewer and

any export for MCAD to reflect the fitted status of the parts. Assembly variants do not affect the

2D PCB layout.

You can add the @VARIANT text string to the schematic to indicate the current

variant on the schematic. This is a useful reminder and particularly important for

printing schematic documentation. See the header block in the schematic reference

manual for more information.

Bill of Materials

Constructing a Bill of Materials is an often necessary but frustrating task at the end of the

schematic design phase. Fortunately, Proteus provides a completely flexible scheme which

allows you to include as much or as little information as required.

Let’s start by looking at the default Bill of Materials Output. Launch the Bill of Materials module

from the application module toolbar at the top of Proteus.
