Return value of specified HDL block-level parameter for specified block



p = hdlget_param(block_path,prop) gets the value of a specified HDL property of the block or subsystem and returns the value to the output variable.

Open the sfir_fixed model. Set the OutputPipeline parameter for the DUT subsystem symmetric_fir to 3 by using the hdlset_param function. Return the value of the OutputPipeline parameter to the variable p by using the hdlget_param function.

open sfir_fixed
p = hdlget_param("sfir_fixed/symmetric_fir","OutputPipeline")
p =


Return HDL block parameters and values for the product block m1 in the symmetric_fir subsystem that is in the sfir_fixed model to the cell array p.

Input Arguments

collapse all

Path to a block or subsystem in the current model.

Example: "modelname/subsysA/blockName"

A string scalar or character vector that designates one of the following:

  • The name of an HDL block property of the block or subsystem specified by path.

  • "all" : If prop is set to "all", hdlget_param returns Name,Value pairs for HDL properties of the specified block or subsystem.

Example: "OutputPipeline"

Output Arguments

collapse all

p stores the value of the HDL block property specified by prop. The data type and dimensions of p depend on the data type and dimensions of the value returned. If prop is set to "all", p is a cell array.


  • Use hdlget_param to obtain the value of HDL block parameters. For a list of block implementation parameters, see HDL Block Properties: General.

  • Use hdldispmdlparams to see the values of HDL model parameters. To obtain the value of general model parameters, use the get_param function.
