Model-based development workflow in Simulink - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start the model simulation.

Simulink

sim('[1]')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using a function name instead of the model name.

Not putting the model name in quotes.

The sim function runs the Simulink model specified by its name as a string. Here, myModel is the model name.

2fill in blank

medium

Complete the code to load the Simulink model into memory.

Simulink

load_system('[1]')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using a function name instead of the model name.

Not using quotes around the model name.

The load_system function loads the Simulink model specified by its name as a string without opening the graphical interface.

3fill in blank

hard

Fix the error in the code to save the model after changes.

Simulink

save_system('[1]')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Trying to save with a function name instead of the model name.

Forgetting to put the model name in quotes.

The save_system function saves the Simulink model specified by its name as a string. This is necessary to keep changes.

4fill in blank

hard

Fill both blanks to create a dictionary of block names and their parameter values.

Simulink

params = {blk: get_param(blk, '[1]') for blk in [2]

Drag options to blanks, or click blank then click option'

AName

BParameters

Cblocks

DblockList

💡 Hint

Common Mistakes

Using incorrect parameter names.

Using a variable name that does not exist.

The get_param function retrieves the value of a parameter (here 'Name') for each block in the list blocks.

5fill in blank

hard

Fill all three blanks to filter blocks with a specific parameter value.

Simulink

filtered = [blk for blk in [1] if get_param(blk, '[2]') == '[3]']

Drag options to blanks, or click blank then click option'

Ablocks

BBlockType

💡 Hint

Common Mistakes

Using wrong parameter names or values.

Using a variable that is not a list of blocks.

This code filters the list blockList to include only blocks whose 'BlockType' parameter equals 'Gain'.
