AIAG & VDA FMEA

Syside Derisker performs safety and reliability analysis according to the AIAG & VDA FMEA Handbook.

Parse and Analyze Failure Modes

Derisker extracts failure modes from your SysML v2 model and automatically computes inherited values like severity, occurrence and detection ratings and uses them to compute the criticality rating. This eliminates manual calculations and ensures consistency across your analysis.

How to Parse

  1. Open Derisker panel (click in left sidebar)

  2. Enter the top level package name of your FMEA model, e.g.

    Derisker_AIAG_ExampleFMEA

  3. Click Parse AIAG & VDA FMEA

The parser automatically checks for any missing or incomplete elements of the FMEA analysis and displays the failure modes in editable table views.

Resulting Table Views

After a successful parse, the data is displayed in a table according to the AIAG & VDA FMEA Handbook format, each row representing a failure mode. There are also tables for viewing failure modes of a specific architectural level.

Automatic Computations

Derisker computes derived values automatically:

Severity

Propagates top-down from effects (higher-severity effects flow to their causes)

Occurrence

Propagates bottom-up from causes (higher probabilities flow upward to effects)

Detectability

Propagates bottom-up from causes (higher detectability ratings flow upward to effects)

Action Priority

Computed using relevant formulas for each analysis type, as specified in the AIAG & VDA FMEA Handbook

Work with Table View

Review and edit failure mode data in an interactive table with bidirectional synchronization to your SysML model.

Table Features

  • View and organize: Customize columns, sort by any field, select rows for navigation

  • Color map: Attributes with associated values have a color map applied to them to help visualize the values

  • Edit properties: Editable cells automatically save changes to the SysML model

  • Navigate to source: Click Go to Source in the right-click context menu to jump to the definition of the element in your SysML file

  • Visualize Failure Chains: Click Visualize Failure Chain in the right-click context menu to visualize the failure chain for a specific failure mode

Note

Not all the attributes are editable. Some columns represent information that is implicit rather than explicit; those fields are not editable directly.

Visualize Failure Chains

Understand how failures propagate through your system with interactive graph visualizations showing cause-effect relationships for any failure mode.

How to Visualize

  1. In table view, select a failure mode row

  2. Click Visualize Failure Chain from the right-click context menu

  3. Graph opens in new panel showing the failure mode and its relationships

Interact with the graph:

  • Navigate: Pan (click and drag), zoom (+/- buttons), reset view

  • Explore nodes: Right-click any node to toggle causes, go to source (SysML), or jump to the table view row for the element (FMEA)

  • Export: Click Export in the top right corner to save the graph as PNG or JPEG

Note

Graphviz must be installed. See Install Graphviz for installation instructions.

Export Results

Share analysis results by exporting visualizations.

How to Export

Export graph to image:

  1. In the failure chain graph view, click Export

  2. Select format (PNG or JPEG) and save location

  3. Image captures current graph layout and zoom level
