Set timed breakpoint in discrete-event simulation
tbreak(t)
tbreak t
tid = tbreak(t)
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.
tid = tbreak(t) returns the identifier of the breakpoint.
t |
Numeric scalar or a string that represents a number. The number is the time of a timed breakpoint. |
tid |
String that represents a breakpoint identifier. |
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.

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