Check model configuration for diagnostic settings that apply to Merge blocks


This check verifies that model configuration parameters are set optimally for Merge blocks for a safety-related application.

Available with Simulink® Check™.

Results and Recommended Actions

ConditionRecommended Action
The diagnostic that detects whether a model contains Merge blocks with more than one driving block executing at the same time step is set to none or warning.

In the Configuration Parameters dialog box, set Detect multiple driving blocks executing at the same time step or set the parameter MergeDetectMultiDrivingBlocksExec to error.

Action Results

Clicking Modify Settings configures model diagnostic settings that apply to solvers and that can impact safety.
