bshow

Highlight block in model with specified block ID during simulation debugging session

Syntax

bshow blk

bshow mdl blk

Description

bshow blk selects and highlights in the block diagram the block in the top model that corresponds to the block ID blk.

You can use this function in a simulation debugging session started:

• Interactively, using the Simulink^® Toolstrip

• Programmatically, using the sldebug function

• Programmatically, using the sim function with the 'debug' name-value argument

Note

This function is available only for simulation debugging sessions started programmatically and for interactive simulation debugging sessions while paused within a time step.

bshow mdl blk selects and highlights in the block diagram the block in the referenced model mdl that corresponds to the block ID blkID.

Input Arguments

blk — Block to show

debugging session block ID

Block to show, specified as a debugging session block ID. The debugging session block ID has the form (t)s:b, where t is the index of the task that contains the block, s is the index of the system that contains the block, and b is the index of the block within the system that contains it.

For a list of block IDs in a model, use the slist function.

mdl — Name of referenced model that contains block

string | character vector

Name of referenced model that contains block, specified as a string or a character vector.

Tips

To start a simulation debugging session interactively, add one or more breakpoints to your model, and in the Breakpoints List, check that Pause within time step is selected. When the simulation pauses on a breakpoint, some of the programmatic debugging commands, such as the stop command, are available for use in the MATLAB^® Command Window.

Version History

Introduced before R2006a

R2024a: sldebug prompt in MATLAB Command Window indicates when simulation debugging session is paused within time step

When you start a simulation debugging session using the Simulink Editor, you can issue some programmatic simulation debugging commands, such as probe or stop, while the simulation is paused within a time step. The sldebug command prompt (sldebug>>) now replaces the MATLAB command prompt (>>) to indicate in the MATLAB Command Window when the simulation is paused within a time step. As in prior releases, you can issue both MATLAB commands and the supported simulation debugging commands at the sldebug command prompt.
