Underspecified initialization detection

Description

Select how Simulink® software handles initialization of initial conditions for conditionally executed subsystems, Merge blocks, subsystem elapsed time, and Discrete-Time Integrator blocks.

Category: Diagnostics

Settings

Default: Simplified

Classic

Initial conditions are initialized the same way they were prior to R2008b.

Simplified

Initial conditions are initialized using the enhanced behavior, which can improve the consistency of simulation results.

Tips

Dependencies

Selecting Classic enables the following parameters:

  • Detect multiple driving blocks executing at the same time step

  • Check undefined subsystem initial output

  • Check runtime output of execution context

Selecting Simplified disables these parameters, and automatically sets Detect multiple driving blocks executing at the same time step to error.
