Debugger Command Summary

The following table lists the debugger commands. The table's Repeat column specifies whether pressing the Return key at the command line repeats the command. See "Simulink Debugger Commands" for a detailed description of each command.

Command	Short Form	Repeat	Description
ashow	as	No	Show an algebraic loop.
atrace	at	No	Set algebraic loop trace level.
bafter	ba	No	Insert a breakpoint after execution of a block.
break	b	No	Insert a breakpoint before execution of a block.
bshow	bs	No	Show a specified block.
clear	cl	No	Clear a breakpoint from a block.
continue	c	Yes	Continue the simulation.
disp	d	Yes	Display a block's I/O when the simulation stops.
help	? or h	No	Display help for debugger commands.
ishow	i	No	Enable or disable display of integration information.
minor	m	No	Enable or disable minor step mode.
nanbreak	na	No	Set or clear break on nonfinite value.
next	n	Yes	Go to start of the next time step.
probe	p	No	Display a block's I/O.
quit	q	No	Abort simulation.
run	r	No	Run the simulation to completion.
slist	sli	No	List a model's nonvirtual blocks.
states	state	No	Display current state values.
status	stat	No	Display debugging options in effect.
step	s	Yes	Step to next block.
stop	sto	No	Stop the simulation.
systems	sys	No	List a model's nonvirtual systems.
tbreak	tb	No	Set or clear a time breakpoint.
trace	tr	Yes	Display a block's I/O each time it executes.
undisp	und	Yes	Remove a block from the debugger's list of display points.
untrace	unt	Yes	Remove a block from the debugger's list of trace points.
xbreak	x	No	Break when the debugger encounters a step-size-limiting state.
zcbreak	zcb	No	Break at nonsampled zero-crossing events.
zclist	zcl	No	List blocks containing nonsampled zero crossings.
