Check multiplier width

Specify whether to check multiplier bit width

Since R2020b

Model Configuration Pane: Global Settings / Coding standards

Description

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

on

Check multiplier width.

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

off

Do not check multiplier width.

To set this property:

Create an HDL coding standard customization object.
```
cso = hdlcoder.CodingStandard('Industry');
```
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;
```
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', ...
        'HDLCodingStandardCustomizations',cso);
```

No recommended settings.

Parameter: MultiplierBitWidth property of hdlcoder.CodingStandard object

Type: character vector

Values: 'on' | 'off'

Default: 'on'

Introduced in R2020b
