sedb.enbreak - Package: sedb

Set breakpoint on operation involving target entity

Syntax

Description

enbreak(enid) or enbreak enid sets a breakpoint for execution or cancellation of the entity with identifier enid in the simulation.

benid = enbreak(enid) returns the identifier of the entity breakpoint.

Input Arguments

enid	String that represents an entity identifier.

Output Arguments

benid

String that represents an entity breakpoint identifier.

Examples

Set a breakpoint on an advancing entity.

1. Begin a debugger session for a particular model. At the MATLAB command prompt, enter:

   sedebug('sedemo_timeout')

2. Proceed in the simulation. At the sedebug>> prompt, enter:

   step over

   The output is:

   %==============================================================================%
   Initializing Time-Based Entity Generators
       %..........................................................................%
       Scheduling EntityGeneration Event (ev1)
       : EventTime = 0.500000000000000
       : Priority  = 1
       : Entity    = <none>
       : Block     = Time-Based Entity Generator
   %==============================================================================%
   Executing EntityGeneration Event (ev1)                Time = 0.500000000000000
   : Entity = <none>                                     Priority = 1
   : Block  = Time-Based Entity Generator

3. Proceed further on in the simulation. At the sedebug>> prompt, again, enter:

   step over

   The output is:

    %..........................................................................%
       Generating Entity (en1)
       : Block = Time-Based Entity Generator
       %..........................................................................%
       Entity Advancing (en1)
       : From = Time-Based Entity Generator
       : To   = Schedule Timeout
       %..........................................................................%
       Scheduling Timeout Event (ev2)
       : EventTime = 1.500000000000000
       : Priority  = 1700
       : Entity    = en1
       : Block     = Schedule Timeout
       %..........................................................................%
       Entity Advancing (en1)
       : From = Schedule Timeout
       : To   = Infinite Server
       %..........................................................................%
       Scheduling ServiceCompletion Event (ev3)
       : EventTime = 0.596864516245641
       : Priority  = 1
       : Entity    = en1
       : Block     = Infinite Server
       %..........................................................................%
       Executing Scope
       : Block = Number of Entities Time-Stamped
       %..........................................................................%
       Scheduling EntityGeneration Event (ev4)
       : EventTime = 1.000000000000000
       : Priority  = 1
       : Entity    = <none>
       : Block     = Time-Based Entity Generator
   %==============================================================================%
   Executing ServiceCompletion Event (ev3)               Time = 0.596864516245641
   : Entity = en1                                        Priority = 1
   : Block  = Infinite Server

4. Set a breakpoint that causes the debugger to stop when it is about to advance the entity, en1.

5. The output confirms the operation:

   Set b1 : Breakpoint for operation involving entity en1

6. Run the simulation until the breakpoint:

   cont

7. The output shows that the debugger hits the entity and stops upon hitting the breakpoint at entity, en1.

   Hit b1 : Breakpoint for operation involving entity en1
   
       %..........................................................................%
       Entity Advancing (en1)
       : From = Infinite Server
       : To   = Cancel Timeout

8. End the debugger session. At the prompt, enter:

   sedb.quit
