Cradle from 3SL, the complete Model Based Systems Engineering Toolsuite, specialising in requirements management, requirements capture, model based systems engineering and for systems engineering software, support and consultancy, the logical choice: Cradle from 3SL.

August 2010 [Cradle 6.3]

Cradle Gateway

Cradle-6.3 introduces a major new Cradle module, Cradle Gateway. Gateway is 3SL’s OEM version of the Reqtify product from Geensoft (www.geensoft.com), who are now a part of Dassault Systèmes. Some other tool vendors also provide OEM versions of Reqtify, and the name Cradle Gateway has been chosen so as to match the family of names created by these other variants.

Gateway is a separately-licensed module with the product code CR-GATE. Being a new module, Gateway is not available to existing customers as part of their existing maintenance agreements. The licensing of Gateway is completely separate to the licensing of all other parts of Cradle. Gateway uses FLEXlm for its licensing, and so Gateway licences are distributed as FLEXlm license.lic files. Both server-based concurrent user licensing and node-locked licensing options are available. Organisations who use FLEXlm for the licence management of other products can add Gateway licence files to their existing FLEXlm licence server.

Gateway provides a traceability management facility between Cradle and a wide variety of external data sources. These data sources can be either documents or data held in other third party tools. A set of couplings (interfaces) are included with the standard Gateway licence and are:

  • Office tools and formats:
    • Word, Excel, Access, PowerPoint, Visio, PowerPoint, Project
    • OpenOffice
    • PDF
    • FrameMaker, Interleaf
  • Software development tools and code:
    • vi, nedit, emacs, Microsoft Visual Studio, TextPad, UltraEdit, Visual C++
    • C, Ada, SDL, VHDL, Verilog, test script files, test log files
  • Requirements management:
    • DOORS, CaliberRM, Requisite Pro
  • Modelling:
    • ARTiSAN Studio, Rose
  • Cradle

Other couplings can be added by special request to 3SL, albeit at additional cost and with a delay whilst a special build of Gateway is created with these couplings added. The additional couplings available are:

  • Simulink
  • MatrixX
  • Clearcase
  • CVS
  • PVCS
  • Dimensions
  • Test Director

Gateway is only available for Windows. Gateway is an optional component inside the Cradle installation file for Windows. Users who wish to install Gateway must choose a Custom installation and select whether the client and/or server components of Gateway are to be installed. Such users must also specifically request a licence from 3SL.

In conjunction with Geensoft, 3SL has extended the capabilities of the underlying Reqtify product to allow it to be used in a distributed, multi-site environment. This capability is unique to the Cradle variant.

Gateway must be used in conjunction with WorkBench. It is started from the Tools menu:

Once started, a project containing any number of data sources can be defined. Each Cradle data source is a query. Gateway will allow users to define cross references between components of each of these data sources. These cross references are the traceability mappings between the data sources. The set of cross references are held within data files created by Gateway. These data files are moved into the Cradle database when Gateway is closed. As such, the traceability mappings are available to all users of a Cradle project, no matter where they are located. Gateway provides a range of powerful facilities to manage these traceability mappings as the underlying data sources (such as Word documents, DOORS modules or Cradle items) are created, deleted or changed.
