RTL Design Rule Parameters

This section contains configuration parameters in the RTL design rules section of the Coding standards tab of the HDL Code Generation > Global Settings pane of the Configuration Parameters dialog box. Use these parameters to check for presence of non-integer constants and the line wrap length in the generated HDL code.

Check for non-integer constants

Specify whether to check for non-integer constants. This check corresponds to CGSL-3.B.D.1 of the Industry standard guidelines.

Settings

Default: On

On: Check for non-integer constants.
Off: Do not check for non-integer constants.

Dependency

To clear the Check for non-integer constants check box, set the HDL coding standard parameter to Industry.

Command-Line Information

To set this property:

Create an HDL coding standard customization object.
```
cso = hdlcoder.CodingStandard('Industry');
```
Set the NonIntegerTypes property of the HDL coding standard customization object.
For example, to disable the check for non-integer constants, enter:
```
cso.NonIntegerTypes.enable = false;
```
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);
```

Check line length

Specify whether to check line lengths in the generated HDL code. This check corresponds to CGSL-3.A.D.5 of the Industry standard guidelines.

Settings

Default: On

On

Check line length.

Maximum: Maximum number of characters in a line, specified as a positive integer. The default is 110.

Off

Do not check line length.

Dependency

To clear the Check line length check box, set the HDL coding standard parameter to Industry.

Command-Line Information

To set this property:

Create an HDL coding standard customization object.
```
cso = hdlcoder.CodingStandard('Industry');
```
Set the LineLength property of the HDL coding standard customization object.
For example, to enable the check line length with a maximum character length of 80, enter:
```
cso.HDLKeywordsLineLength.enable = true;
cso.HDLKeywordsLineLength.length = 80;
```
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);
```
