Introduction

This tool is a drawing tool tailored for generation of electronic schematic diagrams. 

These are diagrams that describe the routing of connections (or wires) between electronic components. 

It includes a netlister and Bill Of Materials (BOM) (a parts list generator) and you can generate publishable schematic diagrams that can also be converted to a standard image format e.g. for use in a web page (as a graphic).

Netlister

The built in netlister checks the schematic for errors such as unconnected pins and wires to ensure that the schematic is correct.  

Additionally double clicking an output netlist entry in the netlister highlights wires in the schematic that created the net.  

This allows the designer to check that the netlist is correct by providing feedback from the netlister to the schematic - to show which wire connection generated which netlist.

Attributes

Unlike an ordinary paint tool this tool adds database information (attributes) to each object so it can analyze the schematic for:

• errors (no duplicate parts etc).
• netlisting (generating a Tango netlist).
• generating a the Bill of Materials (list of parts with attribute data).  
  

Attributes of the selected part are immediately displayed in the screen attribute viewer. You can add your own  attribute data to any library symbol e.g. to associate a specific manufacturer with a part.  You can then output this information via the bill of materials.

Features

You could use a general paint tool to draw a schematic 
but this tool makes it easy because it has:

• A symbol library for repeatedly pasting copies of parts.
• A part database holding attributes for each symbol.
• Symbol pins for identifying connections between symbols.
• Wire and line dragging and merging.
• Automatic connection drawing.
• A Netlister.
• A Bill of Materials generator.

This tool generates three outputs :

• The schematic page (printable and you can also generate a graphic output).
• The netlist.
• The bill of materials.
