sedb.enable - Package: sedb

Enable breakpoints in discrete-event simulation

Syntax

enable id1 id2 id3 ... enable(id_array) enable all

Description

enable id1 id2 id3 ... enables the breakpoint having identifier id. To see breakpoints and their identifiers, use sedb.breakpoints.

enable(id_array) enables the breakpoints in the cell array, id_array.

enable all enables all breakpoints.

Input Arguments

`id`	String that represents a breakpoint identifier.
`id_array`	Cell array of strings that represent breakpoint identifiers.

Examples

Manipulate timed breakpoints and run the simulation until a breakpoint:

Begin a debugger session for a particular model. At the MATLAB command prompt, enter:
```
sedebug('sedemo_timeout')
```

Establish and view breakpoints. At the prompt, enter:

tbreak 0.5
tbreak 1
tbreak 1.5
breakpoints

The output lists the breakpoints:

Set b1 : Breakpoint for first operation at or after time 0.5
Set b2 : Breakpoint for first operation at or after time 1
Set b3 : Breakpoint for first operation at or after time 1.5

List of Breakpoints:

 ID        Type        Value       Enabled
 b1        Timed       0.5         yes
 b2        Timed       1           yes
 b3        Timed       1.5         yes

Delete, disable, and enable some of the breakpoints. View the resulting list:

bdelete b2
disable b3
disable b1
enable b3
breakpoints

The output is:

Deleted b2 : Breakpoint for first operation at or after time 1
Disabled b3 : Breakpoint for first operation at or after time 1.5
Disabled b1 : Breakpoint for first operation at or after time 0.5
Enabled b3 : Breakpoint for first operation at or after time 1.5

List of Breakpoints:

 ID        Type        Value       Enabled
 b1        Timed       0.5         no
 b3        Timed       1.5         yes

Run the simulation until the first enabled breakpoint:

cont

The partial output shows that b3 is the breakpoint at which the debugger stops. The debugger ignores the disabled breakpoint, b1, and does not consider the previously deleted breakpoint, b2.

Hit b3 : Breakpoint for first operation at or after time 1.5
