Overview of traceability matrices and tables (SysML diagram)

Having defined traceability relationships in the model, you can generate Traceability Matrices and Traceability Tables to show traceability relationships between items in a model.

Relationship	Source Item	Destination Item	Description	Related topics
Copy	Requirement	Requirement	Links a master Requirement to a slave Requirement.	• Copy (SysML relationship) • Creating a copy relationship on a requirement diagram • Creating a copy relationship through a Modeler pane
Derive Reqt	Requirement	Requirement	Links a Requirement to Requirements that are derived from it.	• Creating a derive reqt relationship on a requirement diagram. • Creating a derive reqt relationship through a Modeler pane. • Derive reqt (SysML relationship)
Refine	Model item	Model item	Links an item to other items that refine that item.	• Creating a refine relationship on a diagram. • Creating a refine relationship through a pane (UML Standard profile) • Refine (UML Standard profile)
Satisfy	Model item	Requirement	Links a Requirement to items that satisfy that Requirement.	• Creating a satisfy relationship on a requirement diagram (SysML) • Creating a satisfy relationship on a diagram (SysML) • Creating a satisfy relationship through a Modeler pane (SysML) • Satisfy (SysML relationship)
Trace	Model item	Model item	A general purpose link to link an item to other related items.	• Creating a trace relationship on a diagram (UML Standard profile) • Creating a trace relationship through a pane (UML Standard profile) • Trace (UML Standard profile)
Verify	Model item	Requirement	Links a Requirement to items that verify the Requirement.	• Creating a verify relationship on a diagram (SysML) • Creating a verify relationship on a requirement diagram (SysML) • Creating a verify relationship through a Modeler pane (SysML) • Verify (SysML relationship)

A Traceability Matrix shows how items are related to other items through a selected traceability relationship type, that is, Copy, Derive Reqt, Refine, Satisfy, Trace or Verify.

When you open a Traceability Matrix, Modeler creates a table that can be generated as HTML for viewing in your Internet browser, or generated as a Microsoft Excel spreadsheet for viewing in Microsoft Excel. Each time you open a Traceability Matrix, Modeler populates that matrix with the latest data from the model. To specify how matrices and tables are opened for a model: in the Packages pane, right-click the Model, point to Tools > Options, click Matrix/Table Generation Format, and then select HyperTextMarkupLanguage_HTML or Excel_XLS.

Modeler creates a row for each valid source item that is found in the analyzed Packages, and a column for each valid target items of the source items. A cell containing and X indicates that the two associated items are linked through a Copy, Derive Reqt, Refine, Satisfy, Trace or Verify relationship, depending on the type of the Traceability Matrix.

A Traceability Table shows how items are related to other items through a selected traceability relationship type, that is, Copy, Derive Reqt, Refine, Satisfy, Trace or Verify.

When you open a Traceability Table, Modeler creates a table that can be generated as HTML for viewing in your Internet browser, or generated as a Microsoft Excel spreadsheet for viewing in Microsoft Excel. Each time you open a Traceability Table, Modeler populates that table with the latest data from the model. To specify how matrices and tables are opened for a model: in the Packages pane, right-click the Model, point to Tools > Options, click Matrix/Table Generation Format, and then select HyperTextMarkupLanguage_HTML or Excel_XLS.

Modeler creates a row for each valid source item that is found in the analyzed Packages, and the columns show valid target items of the source items. You can add additional columns to show other properties of the table items.
