Methods and Standards

Smart Perspectives

Switching between perspectives was significantly improved for this release. Now when you change the perspective, the project is not converted to another framework.  Only the graphical user interface changes. If you intend to convert the project, you need to do that manually.

New Resources to Capability Mapping matrix

Resources to Capabilities Mapping (Rs-Tr) addresses the direct and indirect linkage between Resources (Enterprise Phase, Operational Agent, Resource Performer, Service Specification, Actual Enterprise Phase, Actual Enduring Task ) described in the Resources domain and Capabilities specified in the Strategy domain. 

BPMN Compliance Mode improvements

The BPMN Compliance Mode improvements are as follows:

  • When you turn the mode on in a UAF project, BPMN stereotypes are applied to all UAF elements.
  • The BPMN Traceability matrices, maps, and tables are included in the UAF project.
  • Improved reports.


Diagramming Improvements

In the Phasing Gantt charts, you can choose to highlight Capabilities when their Sub Capabilities were removed from the chart. You can also choose the highlight color.

Top Capability display conditions

In the Chart Properties dialog, you can now choose a condition to highlight the availability of capabilities. There are two available options:

  • Select AND condition to highlight the Top Capability bar in red when any capability is unavailable in that period of time, and in black when all sub capabilities are available.
  • Select OR to highlight the Top Capability bar in black when any sub capability is available.

Easy Process Flow Diagrams Creation

Now you can conveniently create Process Flow diagrams from the Process diagram with the defined aggregation/composition of activities/functions.

Usability Improvements
  • Zooming in all Gantt Chart diagrams has been updated to be consistent with zooming in diagrams. Now the Ctrl+Scroll up or down will zoom the entire Chart and Shift+Scroll will control the timeline.


SysML Features

SysML model transformation to Simulink and Modelica


19.0 sp3 version allows users to export standard SysML models into Simulink (incl. Stateflow, Simscape) and Modelica models based on a standard mapping provided by new OMG SysPhS specification (SysML Extension for Physical Interaction and Signal Flow Simulation).


This one-way transformation supports both black-box or full implementation which includes parametrics, statemachines, internal structures with ports, interfaces and connectors.

Simulink Import

The SysML plugin has undergone some major improvements. Simulink model files can now be imported and represented as SysML Blackbox Blocks. Once the file is imported, you can select input and output ports to be represented as Flow ports on the Block. Additionally, the imported Simulink model can be simulated using the Cameo Simulation Toolkit.

Contextual Relationships

  • Enhance your modeling experience – contextualize Allocate, Refine, Satisfy, Trace, and Verify relationships to consider the context the connected properties are used in. Beginning with this release, users can more easily create and keep contextual relationships up to date in diagrams and matrices. 

Creating contextual relationships to define the context they are used in
  • You can now drag and drop the property directly on the Requirement shape in the symbol diagram to create the contextual Satisfy relationship automatically.

Flow Management Improvements

In the SysML Internal Block Diagram, the automatic delegation functionality:

  • creates a connector from the port to the nearest border. 

  • creates connectors with relevant ports between the ports of the nested parts (delegate).

  • realizes the existing flows on the newly created connectors.

Instance Improvements

  • Now you can save instance values to Blocks as default values. Learn more >>

  • The naming of the nested parts created by Create Instance wizard or in the Instance Table is improved.

  • The new Clone with parts action in the Instance Table toolbar and selected row's shortcut menu copies not only the selected Instance but its nested parts as well.

Other SysML features

  • Pins for the Opaque Actions can now be created automatically. Learn more >>
  • For your convenience, Requirements are now also shown within the elements that satisfy them in the Structure tree.

Modeling and Infrastructure

Model-Based Product Line Engineering

Product Line Engineering has been significantly extended by implementing the Model-Based Product Line Engineering (MBPLE) capability. In addition to integration with PLE tools (Big Lever Software Gears and Pure Variants), it is now possible to perform PLE in modeling tools without using third-party tools.

        

Learn more about MBPLE >> 

ISO 26262 Functional Safety Plugin

We are proud to introduce the brand new ISO 26262 Functional Safety Plugin. This plugin tightly integrates functional safety with MBSE (requires SysML plugin or Cameo Systems Modeler) and supports the ISO 26262 standard (the adaptation of IEC 61508) designed to comply with needs specific to the application sector of Electric & Electronic (E/E) systems within road vehicles. The ISO 26262 Functional Safety Plugin provides end-users with the means to perform hazard analysis and risk assessment:

  • Define Malfunctioning Behaviors for each Function

  • Specify an Operational Condition Library

  • Define Operational Situations as a combination of Conditions

  • Combine Malfunctioning Behaviors with Operational Situations to define Accident Scenarios

  • Specify a Hazard Library

  • Define System Level and Vehicle Level Effects

  • Combine Hazards, Effects, and Accident Scenarios into Hazardous Events

The plugin also provides a way to define functional safety concepts (safety requirements and perform ASIL decomposition) as well as generate safety reports. 


A HARA Table allows you to define Hazardous Events as a combination of Hazards, Effects, and an Accident Scenario. The description area shows all the information about the selected Hazardous Event.

Learn how to use the ISO 26262 Functional Safety Plugin >>

Custom Hierarchy in Tables

Modelers now have more freedom to decide how to organize elements in tables. Simply choose one of the tree-view options to display elements hierarchically and see the changes in the table structure reflect the criterion you have specified:

• Containment: displays the decomposition of elements related by Containment.
• Structure: displays the decomposition of Part properties related by Composition.
• Custom: displays the decomposition of elements related by any specified criteria.

Building a custom hierarchy in a table

Stay up to date with the changes in your model by enabling the Suspect Links tracking. You can now track the changes applied to requirements linked to other model elements, as well as keep track of the changes that affect the selected model elements at the chosen end (source or target) of the specified dependencies.

Configuring Suspect Links tracking in the model

Further Improvements

  • Now you can create nested structures quickly by pasting structural lists on Composite Structure and Internal Block diagrams.
  • To quickly create Activity Actions you can simply paste a copied list from any source of information. The Actions will be created and connected.
  • ReqIF import/export has been improved as well. From now on, all existing images are attached to the model upon ReqIF import and added to the ReqIF file upon export. 
  • ID prefixes no longer come with the applied HTML styles. Instead, all IDs are imported/exported as plain text. 

  • It is now possible to specify the element properties to be shown on the shape by default in a few clicks.

  • You can now wrap long text into multiple lines to display all of it in a table cell.

  • The modeling tool now allows entering an unlimited number of entries into the table cell to enable displaying multiple values/plain text lines in a table cell.

  • To save time, you can now create multiple relationships in matrices simultaneously.
  • The redesigned Documentation property group in the Specification window allows you to have all comments annotating model elements in one place as well as create and manage them easily when needed.

Know your changes - Used Project Update Impact Analysis

The used project update impact analysis minimizes the risks of introducing unexpected and unwanted changes to the main project. Previous tool versions required you to switch used project versions pretty much blindly and hope for the best. Most of these blind updates caused main project composition integrity errors, such as recovered elements. Solving these errors was extremely frustrating and a time-consuming task. Thus, we created a new feature, providing you with early insights into the impact a used project version switch brings to the main project. You are then have the freedom to easily accept, reject the changes, or choose a different target used project version altogether.

You can use the analysis to inspect impacting changes at different granularity levels, allowing you to see the impact on element-to-element usages or to dive deeper into specific affecting/affected element properties. Differently colored changes allow quickly distinguishing between addition, modification or deletion changes. We are sure the used project updated impact analysis will deliver the value that comes from early change insights and better decision-making experience in general.

Merge Tool Usability Enhancements

Since merging itself is a relatively complex procedure, requiring deep understanding of model changes, in this release we deliver multiple enhancements oriented towards better UI usability and change analysis flexibility:

  • Merge Result Preview, column filtering. Ever felt lost because you are not completely sure what kind of element changes the final merged project will have? The new Merge Result Preview column lets you inspect final changes at property level changes before merging is complete. Additionally, as we introduced a new Merge Result Preview column, we added the ability to show/hide selected columns. For example, by default, we hide the Ancestor column, to prevent confusion when there are no conflicts. However, you can select to show Ancestor again, in case it is needed to solve conflicts.
  • Change presentation and filtering. Are you tired of always expanding the element tree to find a wanted element? From now on, all changed elements can also be represented in the flat list-view. Furthermore, use a search bar to find the exact name of the element you want to check. You say that this small feature is no help where there is a number of similarly named elements? Another enhancement, change filters, will come in handy. Change filters are introduced not only for the flat list-view but also for the tree-view. All change filters are presented in one categorized menu. 
  • Accept/Reject changes improvements. Work even smarter with the improved Accept/Reject buttons. We have combined the Accept/Reject buttons with the Go to next button. Easily go through all changes with a combined action and no more wandering around the Merge dialog, going back and forth to select and accept/reject another change. Furthermore, the specification panel was enriched with the ability to accept/reject property changes directly via a shortcut menu in the selected contributing column (Source or Target).

Other Enhancements 

  • Together with the used project update impact analysis, we introduce a Used by Project shortcut menu for quickly reviewing how the main project uses elements from a particular used project.
  • We are introducing an advanced memory tracking mechanism. This mechanism will track and notify you when the tool is running out of allocated memory, and suggests that you revisit your Memory Settings.
  • The implemented detailed project statistics feature calculates whole project statistics and exports results to a separate file. This is a quick and easy way to provide statistics to the support team when dealing with issues or share them internally for your own needs.
  • For a better user experience and more intuitive workflow, we have introduced shortcut menus for common project usage-related actions in the Project Usages dialog. 
  • For security matters we now hide TWCloud project categories in the modeling tool dialogs if a user does not have Categorize Resources permission or Read-Only permission for at least one project inside these categories.
