RTL Description Rules for Conditional Parameterss

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 for conditional and if-else statements that are specified by the Industry standard guidelines.

Check for conditional statements in processes

Specify whether to check for length of conditional statements that are described separately within a process. This check corresponds to CGSL-2.F.B.1 of the Industry standard guidelines.

Settings

Default: On

On: Check for length of conditional statements in a process. The default length is 1.
Off: Do not check for length of conditional statements in a process.

Dependency

To clear the Check for conditional statements in processes 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 ConditionalRegionCheck property of the HDL coding standard customization object.
For example, to check for four conditional statements in a process, enter:
```
cso.ConditionalRegionCheck.enable = true;
cso.ConditionalRegionCheck.length = 4;
```
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 if-else statement chain length

Specify whether to check if-else statement chain length. This check corresponds to CGSL-2.G.C.1c of the Industry standard guidelines.

Settings

Default: On

On

Check if-else statement chain length.

Length: Maximum if-else statement chain length, specified as a positive integer. The default is 7.

Off

Do not check if-else statement chain length.

Dependency

To clear the Check if-else statement chain 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 IfElseChain property of the HDL coding standard customization object.
For example, to check for if-else statement chains with length greater than 5, enter:
```
cso.IfElseChain.enable = true;
cso.IfElseChain.length = 5;
```
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 if-else statement nesting depth

Specify whether to check if-else statement nesting depth. This check corresponds to CGSL-2.G.C.1a of the Industry standard guidelines.

Settings

Default: On

On

Check if-else statement nesting depth.

Depth: Maximum if-else statement nesting depth, specified as a positive integer. The default is 3.

Off

Do not check if-else statement nesting depth.

Dependency

To clear the Check if-else statement nesting depth 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 IfElseNesting property of the HDL coding standard customization object.
For example, to enable the check for if-else statement nesting depth with a maximum depth of 5, enter:
```
cso.IfElseNesting.enable = true;
cso.IfElseNesting.depth = 5;
```
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);
```
