Automatic ARINC 661 Server Generation

SCADE Server Creator for ARINC 661 Compliant Systems enables aircraft manufacturers and CDS developers to automatically generate the majority of the ARINC 661 server C source code, including:

  • The widgets library C source code generated from the widget models (created with SCADE Widget Creator or delivered in the SCADE Widgets Library) by using SCADE Suite KCG and SCADE Display KCG
  • The C code corresponding to the widget-dependent parts of the ARINC 661 server — such as DF parsing, server-side communication protocol management, windows and layers logic, drawing scheme, etc. — from a set of ARINC 661 Configuration Files

Automatic generation of the ARINC 661 server source code

  • Automatic generation of a readable and printable report from the “ARINC 661 Configuration” files, describing the parameters, creation structure, event structures or runtime modifiable parameters tables for each widget with the same layout as the ARINC 661 standard specification
  • Source code of a configurable ARINC 661 Server
  • Automatic generation of binary ARINC 661 Widgets Library, for integration as a WYSIWYG (What You See Is What You Get) environment, into the SCADE UA Page Creator for ARINC 661
  • Automatic C source code generation, for integration into the ARINC 661 Server, from an ARINC 661 widgets library
  • Support of Symbols and Pictures Graphical Definition
  • Support of GBK/UTF-8 character sets (according to ARINC 661-5 supplement)

In addition to the code generated by SCADE Server Creator, the Server code is completed by C source code corresponding to:

  • The core part of the server, independent from the platform architecture (RTOS /HW/ drivers), which contains the common services and structures used by various parts of the Server. Modifying this part is required only if new or custom capabilities are needed in the Server.
  • The architecture part of the platform-dependent part of the Server, which includes the main loop, the I/O dispatching, OpenGL/video initialization and the definition of the windows and layers configuration. This part requires end-user customization to match the architecture of the target.

SCADE Server Creator also enables automatic generation of an executable ARINC 661 server for Windows/PC host machines from the ARINC 661 Widgets Library and Configuration Data.

Generated Server Characteristics

  • Portable (natively works under Windows and Linux)
  • Configurable through the ARINC 661 configuration files (customizable list of widgets, customizable widget interfaces — definition or runtime parameters, events, etc. — and customizable dependencies between widgets)
  • Configurable part of the ARINC 661 Server automatically generated by Server Creator
  • Limited and well-identified platform dependencies (such as memory management, graphics resource access, main scheduling, etc.)
  • Multi UA support, multi DF support
  • Mixing ARINC 661 pages with multiple SCADE Display-generated “symbology” layers
  • Management of several Display Units (DU), Windows and Layers “configurations” automatically generated from XML configuration files
  • Run-time reconfiguration of the DUs, Windows and Layers
  • Multicursor support, multiple “keyboard-like” devices support
  • Communication protocol based on Ethernet and TCP/IP (customizable by the user)
  • Configurable resources and style sets as binary data
