Explore the D/D/1 System Using the SimEvents Debugger

The plot in “Run the Simulation” on page 2-13 indicates how many entities have

departed from the server, but does not address the following question: Is any entity still

in the server at the conclusion of the simulation? To answer the question, you can use the

SimEvents debugger, as described in this section. Using the debugger involves running

the simulation in a special debugging mode that lets you suspend a simulation at each

step or breakpoint and query simulation behavior. Using the debugger does not require

you to change the model. The topics in this section are as follows:

• “Start the Debugger” on page 2-17

• “Run the Simulation” on page 2-18

• “Query the Server Block” on page 2-18

• “End the Simulation” on page 2-19

• “For Further Information” on page 2-19

Start the Debugger

To open a completed version of the example model for this tutorial, enter

simeventsdocex('doc_dd1') in the MATLAB Command Window. Save the model in your

working folder as dd1.

To start simulating the current system in debugging mode, enter this command at the

MATLAB command prompt:

sedebug(bdroot)

The output in the MATLAB Command Window indicates that the debugger is active. The

output also includes hyperlinks to information sources.
