Find blocks in Simulink models

collapse all in page

Syntax

bl = Simulink.findBlocks(sys)
bl = Simulink.findBlocks(sys,options)
bl = Simulink.findBlocks(sys,Param1,Value1,...,ParamN,ValueN)
bl = Simulink.findBlocks(sys,Param1,Value1,...,ParamN,ValueN,options)

Description

bl = Simulink.findBlocks(sys) returns handles to all blocks in the model or subsystem sys.

example

bl = Simulink.findBlocks(sys,options) finds blocks that match the criteria specified by a Simulink.FindOptions object.

example

bl = Simulink.findBlocks(sys,Param1,Value1,...,ParamN,ValueN) finds blocks whose block parameters have the specified values.

example

bl = Simulink.findBlocks(sys,Param1,Value1,...,ParamN,ValueN,options) finds blocks whose parameters have the specified values and that match the criteria specified by a FindOptions object.

Search for Block by Name

Open the example. Then, load the vdp model.

open_system('vdp')

Get the handle of the block named x1.

Simulink.findBlocks('vdp','Name','x1')
ans = 
186.0006

Search for Blocks of Specific Type

Get the handles of all Sum blocks in the vdp model.

Simulink.findBlocks('vdp','BlockType','Sum')
ans = 2×1

  178.0009
  182.0006

Search for Blocks With Specific Parameter Value

Get the handles of all blocks in the vdp model whose Saturate On Integer Overflow parameter has the value 'on'.

Simulink.findBlocks('vdp','SaturateOnIntegerOverflow','on')
ans = 4×1

  167.0004
  175.0005
  178.0009
  182.0006

The function returns the handle of the two Sum blocks, the Product block, and the Square block in the vdp model.

Search for Blocks of Specific Type With Specific Parameter Value

Get the handles of all Sum blocks in the vdp model whose List of Signs parameter value is '+-'. 

Simulink.findBlocks('vdp','ListofSigns','+-','BlockType','Sum')
ans = 
182.0006

The function returns the handle of the Sum block named Sum1.
