Begin a debugger session for a particular model. At the MATLAB command prompt, enter:
```
sedebug('sedemo_count_attributes')
```
Use the current time to set a breakpoint. At the sedebug>> prompt, enter:
```
t = simtime;
tbreak(t+2)
```
The following output confirms the setting of the breakpoint:
```
Set b1 : Breakpoint for first operation at or after time 2
```

Run the simulation until the breakpoint:

cont

The output describes simulation behavior and then confirms that the debugger has reached the breakpoint. Here is an excerpt:

Hit b1 : Breakpoint for first operation at or after time 2

End the debugger session. At the sedebug>> prompt, enter:
```
sedb.quit
```
