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');

set_param('MyModel/Time-Based Entity Generator','position',[65 63 150 117]);

The position parameter specifies the top left (x,y) and lower right (x+block width, y+block height) corners of the block.

Add the FIFO Queue block and position it.

add_block('simeventslib/Queues/FIFO Queue','MyModel/FIFO Queue');

set_param('MyModel/FIFO Queue','position',[195 63 280 117]);

Get the port handles for each block.

Block1PortHandles = get_param('MyModel/Time-Based Entity Generator','PortHandles');

Block2PortHandles = get_param('MyModel/FIFO Queue','PortHandles');

Block port handles are structure variables that contain the elements LConn and RConn. These elements represent the block left and right connection ports.

Connect the blocks.

add_line('MyModel',Block1PortHandles.RConn(1), Block2PortHandles.LConn(1),'autorouting','on');

Port indices, such as RConn(1), correspond to the top-down order of connection ports when you look at the block in the Simulink Editor. The autorouting feature routes lines around any intervening blocks or other lines, as needed.
