Frequently Asked Questions

Look below for answers to the most common questions we are asked about research and development, model-based systems engineering or our EDICT® Tool Suite, WWTG has the answers.


What does EDICT® stand for?
EDICT® is the Elicitation, Design, Integration and Certification Tool.
What is basic purpose of EDICT®?

EDICT® is a suite of Model Based Engineering tools based on the EDICT® Modeler platform. This platform provides a central way to bring together information for stakeholders throughout a system design lifecycle. EDICT® provides tools for the ideation, design, evaluation, analysis, certification and documentation of complex designs across multiple domains.

What modeling language is EDICT based on?

Models built graphically in EDICT are represented in Architecture Analysis and Design Language (AADL).  In addition, EDICT can input and output AADL representations of models.

Is EDICT® an AADL editor?

EDICT® is not a native AADL editor. It provides modeling capabilities that are more extensive and richer than what AADL can support.  However, EDICT® provides extensive support for the AADL language through the optional AADL Adapter Extension. This extension supports importing AADL designs, exporting to AADL models, and integrating with other AADL tools such as OSATE.

Is EDICT® modular?

EDICT® is designed and built as a completely modular toolset. EDICT® is built using Eclipse technology, which provides a modular and extensible framework for applications and integration between Eclipse tools. This allows EDICT to be configured with the specific toolset configuration needed by any customer.

Is EDICT® an Enterprise Application?”

EDICT® is a fully-supported commercial application that can be purchased by customers. EDICT® supports use by both individual users, as well as a team of users across multiple workspaces and development roles. A variety of commercial and enterprise workflows are supported, including revision control tools, model distribution restrictions, and diversification of team roles.

What format does EDICT® use to store designs?

EDICT® uses the XML language to persist project materials and designs in a standardized manner.

In what formats can EDICT® designs be exported?
  • EDICT® projects can be exported wholesale as a complete set of XML models and related artifacts.
  • EDICT® Project visual components can be exported as an HTML report set.
  • System Architectures can be exported to AADL or as XML or CSV models.
  • Individual architecture diagrams can be exported to images.
  • Microsoft Word (.docx) reports are available for select analysis.




Can EDICT® perform a particular model analysis that I need?

Yes, the capability you need can be added to the EDICT® Tool Suite if it is not already available. Click here to Contact Us for more information on contracting for custom analysis requirements.

How can I learn more about EDICT?

Click here to learn more about EDICT®, here for information about EDICT Training, or here to contact us for more information.”

How can I purchase EDICT?

The EDICT® Tool Suite is modular.  The EDICT Modeler tool is sold separate from its extensions.  Click here to purchase the EDICT Modeler online or Click on Contact Us to request a quote based on your needs.

Is there a free evaluation version for EDICT®?

Yes, there is a free 30-day evaluation version of EDICT®. The purpose of the evaluation version is to enable you to assess its applicability to your applications.  Although some capabilities are omitted form the evaluation version, you will be able to continue building upon your modeling and analysis developed with it in the full version after purchase of the full version.

What is MBSE?

MBSE stands for Model-Based Systems Engineering.  MBSE incorporates modeling and analysis of a system throughout its life cycle from requirements elicitation, through design, development, testing, deployment, maintenance and even retirement.
