Altium schematic file format

Altium ".SchDoc" files use the OLE compound document format. Inside the OLE container are streams (embedded files). The main stream contains schematic object records. Each record is a collection of properties, encoded as ASCII or byte strings.

Contents:

OLE compound document

The OLE root directory lists up to three streams: FileHeader, Storage, and Additional. The schematic data is in the FileHeader stream.

The Storage stream has a similar header to FileHeader's header, except that the text is |HEADER=Icon storage. It contains embedded files for Image objects.

The Additional stream is not always present. It has the same header as FileHeader, and it seems any extra records belong after the sequence of records from the FileHeader stream.

Each stream seems to be a sequence of object records. Pluciński calls them primitives; Protel calls specific PCB objects either primitives or group objects. Upverter calls them parts.

Record format:

  • Length of the payload: (little endian encoding, 2 bytes)
  • 0 (1 byte)
  • Record type (1 byte)

If the record type is 0, it is a property list, followed by a null terminator byte. Records in the Storage stream, after the initial header record, have type 1, and the following format:

  • 0xD0 (1 byte)
  • Filename length (1 byte)
  • Filename
  • Compressed size (little-endian encoding, 4 bytes)
  • zlib-compressed data (including a zlib header)

Property list

Properties (so called by Upverter and Protel) within a property list are separated by a pipe “|” character. For most records the list starts with pipe character as well (except for RECORD=28). Most property names are in all capitals, with words run together without underscores or any other punctuation. Exceptions include |DISPLAY_UNIT for sheet objects, and some properties for co-ordinates. Property names are probably case-insensitive.

Sometimes properties are repeated, such as |HOTSPOTGRIDON=T in the Sheet record.

Data types

Some simple common data types represented by properties:

  • Strings: Most properties are directly decodable as ASCII strings. Non-ASCII strings often use Windows CP-1252 or some similar encoding, and are often accompanied by another property encoded in UTF-8.
  • Co-ordinate pairs (points): |LOCATION.X=200|LOCATION.Y=100
  • Lists: |FONTIDCOUNT=2|SIZE1=10|FONTNAME1=. . .|SIZE2=10|FONTNAME2=. . .
  • Co-ordinate lists: |LOCATIONCOUNT=2|X1=100|Y1=100|X2=200|Y2=100
  • TRotateBy90: An enumerated integer type. Default is 0 (rightwards).

The origin (0, 0) is at the bottom left corner, and the y values increase from bottom to top. Sizes and locations are in units of 1/100″ = 10 mils = 0.254 mm. Each dimension or co-ordinate is usually given as an integer property. Sometimes a second integer property with a _FRAC suffix is also given, maybe measured as a fraction of 100,000 units.

Integers

Decimal integers: |RECORD=31, |OWNERPARTID=-1. Default value if property is missing seems to be 0.

  • Enumerated types: |RECORD=1/2/. . ., |RECORD=17|STYLE=1/2/. . .
  • Bitfields: |COLOR=8388608 (= 0x800000), |PINCONGLOMERATE=58 (= 0x3A)

Colours

RGB colours: |COLOR=128|AREACOLOR=11599871 (= #800000, #FFFFB0). Inherited from Delphi TColor data type.

  • Bits 0–7, mask 0x0000FF: Red
  • Bits 8–15, mask 0x00FF00: Green
  • Bits 16–23, mask 0xFF0000: Blue

Real numbers

Decimal numbers with a fractional part: |ENDANGLE=360.000, encoding angles. Typically three decimal places. Property omitted when the value is zero.

Boolean

|ISHIDDEN=T|PARTIDLOCKED=F. When false, the property is often omitted, rather than explicitly set to F.

Line width

|LINEWIDTH

  • Omitted: 4 mil
  • 1: 10 mil
  • 2: 20 mil
  • 3: 40 mil

Object records

Each item in the FileHeader stream describes an object. The first object is a Header object. All subsequent objects are indexed starting from zero. The type of each object is identified by its |RECORD property.

Indexed objects have a hierarchical ownership relationship with each other, and are stored in depth-first order. The object at index zero directly follows the header object, and is a Sheet object.

If a property is given with a value below, that documents that it has only ever been seen with that particular value.

Header

This object does not have a |RECORD property, but could be interpreted as being equivalent to setting |RECORD=0.
