Check multiplier width

Specify whether to check multiplier bit width

Since R2020b

Model Configuration Pane: Global Settings / Coding standards


Specify whether to check multiplier bit width. This check corresponds to CGSL-2.J.F.5 of the Industry standard guidelines.


To clear the Check multiplier width check box, set the HDL coding standard parameter to Industry.


on (default) | off

Default: On


Check multiplier width.


Maximum multiplier bit width, specified as a positive integer. The default is 16.


Do not check multiplier width.


To set this property:

  1. Create an HDL coding standard customization object.

    cso = hdlcoder.CodingStandard('Industry');

  2. Set the MultiplierBitWidth property of the HDL coding standard customization object.

    For example, to enable the check for multiplier width with a maximum bit width of 32, enter:

    cso.MultiplierBitWidth.enable = true;
    cso.MultiplierBitWidth.width = 32;

  3. Set the HDLCodingStandardCustomizations property to the HDL coding standard customization object, specify the coding standard, and generate code.

    For example, if your DUT is sfir_fixed/symmetric_fir, enter:

    makehdl('sfir_fixed/symmetric_fir', 'HDLCodingStandard','Industry', ...
