sedb.tbreak - Package: sedb

Set timed breakpoint in discrete-event simulation

Syntax

tbreak(t) tbreak t tid = tbreak(t)

Description

tbreak(t) or tbreak t, at the SimEvents debugger command prompt, sets a breakpoint for time t. If you later enter cont, the simulation stops at the first operation at or after time t. The argument, t, is a numeric scalar or a string that represents a number.

tid = tbreak(t) returns the identifier of the breakpoint.

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 sedebug>> 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 0.500000
Set b2 : Breakpoint for first operation at or after time 1.000000
Set b3 : Breakpoint for first operation at or after time 1.500000

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 1.000000
Disabled b3 : Breakpoint for first operation at or after time 1.500000
Disabled b1 : Breakpoint for first operation at or after time 0.500000
Enabled b3 : Breakpoint for first operation at or after time 1.500000

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 1.500000
