PCB123 XML Neutral Library Format Specification

PCB123 XML Neutral Library Format Specification

OverviewThe PCB123 layout system has adopted XML for its data interchange format. XML is a hugely popular standard developed by the World Wide Web Consortium (W3C) that was designed to transport virtually any type of data in a highly organized format which can be checked for syntactic and even semantic correctness automatically by a conforming XML reader.

If you are only interested in learning the XML NLF format to make hand edits to existing files then you can skip ahead to the format description to learn about the different object records and their fields. However, if you plan on programmatically reading or emitting XML NLF files then the following information may prove beneficial.

XML ImplementationIf you are not familiar with the XML format and XML terminology then it is recommended that you take a look at the W3C web portal at www.w3c.org. This site has a vast repository of all things XML including introductory material.

First, you may be interested to know that Sunstone provides a fairly comprehensive schema for the XML NLF file format. The schema is available in both the W3C Schema Definition (.xsd) and native Document Type Definition (.dtd). To obtain these schema definitions please visit www.pcb123.com. Validating and checking an XML NLF file for well-formedness against this schema almost ensures the file will load without problems into the PCB123 system.

The XML NLF format was structured as a hierarchical database with an eye almost exclusively toward XML DOM parsing. Virtually no consideration has been made for a SAX reader due to the difficulties in writing a robust stream reader for hierarchical structures. The DOM is much more natural and the XML NLF has been structured to make this particularly true.

XML NLF elements do not contain text data. All PCB objects are described as elements whose data are defined in element attributes. Describing all the fields of an object in specific name/value attribute pairs insulates the parser and emitter from format changes and allows for the loading of object values in any order desired.

NLF Format DescriptionNLF elements define the hierarchical data structure but it is the element attributes that carry the actual data.

The diagram below shows the basic hierarchical relationship of all the elements in the XML NLF format.

http://www.pcb123.com/

http://www.w3c.org/

Below, each element description begins with a picture of the semantic relationship with other elements. The meaning of the symbols are as follows:

Indicates a choice of child elements in any order.

Indicates a choice of zero or more child elements in any order.

Indicates a sequence of zero or more child elements in a set order.

The semantic diagram for each element is followed by a table of the recognized attributes for that element. Each attribute will indicate if it is required or optional, its default value, and its range. Except where noted, there are no limits to the number of elements in an NLF file nor are there any limits on such things as string lengths.

Many attributes use uniform syntactic and semantic rules. They are as follows:

Attribute type Rule Example

in = inchescm = centimentersmm = millimetersmil = mils (thousands of an inch)

If no suffix is supplied, the default is assumed to be inches.

Pin Element

The Pin element defines a pin (or pad) object in the database. The pin will be a child of its parent element.

An exception to this rule is when a component pin has no name – you may have as many unnamed pins in a component as you want. If a pin is not owned by a component, but rather is a board-level entity then there are no specific rules governing the name of the pin, though it is recommended that they be created without names so as a unique, hidden name will be automatically generated for the pin.
