Other RTL Description Rule Parameters
These parameters belong to the RTL description 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 customize RTL description rules of the Industry standard guidelines. These rules pertain to checking the multiplier width, whether to minimize use of variables, and initial statements to provide initial value for RAMs.
Minimize use of variables
Specify whether to minimize use of variables. This check corresponds to CGSL-2.G of the Industry standard guidelines.
Settings
Default: Off
On
Minimize use of variables.
Off
Do not minimize use of variables.
Dependency
To select the Minimize use of variables 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
MinimizeVariableUsage
property of the HDL coding standard customization object.For example, to minimize use of variables, enter:
cso.MinimizeVariableUsage.enable = true;
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 for initial statements that set RAM initial values
Specify whether to check for initial statements that set RAM initial values. This check corresponds to CGSL-2.C.D.1 of the Industry standard guidelines.
Settings
Default: On
On
Check for initial statements that set RAM initial values
Off
Do not check for initial statements that set RAM initial values.
Dependency
To clear the Check for initial statements that set RAM initial
values 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
InitialStatements
property of the HDL coding standard customization object.For example, to disable the check for initial statements that set RAM initial values, enter:
cso.InitialStatements.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 multiplier width
Specify whether to check multiplier bit width. This check corresponds to CGSL-2.J.F.5 of the Industry standard guidelines.
Settings
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.
Dependency
To clear the Check multiplier width 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
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);
