Build a Discrete-Event Model

2-15

• Starting at T=1, the plot is a stairstep plot. The stairs have height 1 because the

server processes one entity at a time, so entities depart one at a time. The stairs have

width equal to the constant service time, which is one second.

Insert Blocks

You can insert a block in an existing line, if the block that you want to insert:

• Has only one input and one output port.

• Has connection port types (i.e. entity ports or signal ports) that correspond with the

data on the existing line. For example, in an existing entity line, you can insert only

a block that accepts and outputs entities. You cannot insert a block that accepts and

outputs event-based signals.

To insert a block in a line:

Drag the block over the line.

Release the mouse button. SimEvents inserts the block in the line.

Build a Model Using Model Construction Commands

This example shows how to use model construction commands to add blocks to a model

and connect them.

Suppose you want to add a Time-Based Entity Generator block and a FIFO Queue block

to a model and connect them:

This procedure shows you how to add and position the two blocks in a model, for

example, MyModel.

Add the Time-Based Entity Generator block and position it.

add_block(['simeventslib/Generators/Entity Generators/', ...

'Time-Based Entity Generator'], 'MyModel/Time-Based Entity Generator');
