Syntax

cso = hdlcoder.CodingStandard(standardName)

Description

example

cso = hdlcoder.CodingStandard(standardName) creates an HDL coding standard customization object that you can use to customize the rules and the appearance of the coding standard report.

If you do not want to customize the rules or appearance of the coding standard report, you do not need to create an HDL coding standard customization object.

Examples

collapse all

Create an HDL coding standard customization object, cso.

cso = hdlcoder.CodingStandard('Industry');

Customize the coding standard options as follows:

  • Do not show passing rules in the coding standard report.

  • Set the maximum if-else nesting depth to 2.

  • Disable the check for line length.

cso.ShowPassingRules.enable = false;
cso.IfElseNesting.depth = 2;
cso.LineLength.enable = false;

Create an HDL codegen configuration object.

hdlcfg = coder.config('hdl');

Specify the coding standard and coding standard customization object.

hdlcfg.HDLCodingStandard = 'Industry';
hdlcfg.HDLCodingStandardCustomizations = cso;

Specify your test bench function name. In this example, the test bench function is mlhdlc_dti_tb.

hdlcfg.TestBenchName = 'mlhdlc_dti_tb';

Generate HDL code for the design and check the code according to the customized HDL coding standard rules. In this example, the design function is mlhdlc_dti.

codegen -config hdlcfg mlhdlc_dti
Open Script

Create an HDL coding standard customization object

  • Load the sfir_fixed model

  • Create a coding standard customization object cso

load_system('sfir_fixed')
cso = hdlcoder.CodingStandard('Industry');

Customize the coding standard options

  • Do not show passing rules in the report.

  • Set maximum line length to 80 characters.

  • Check that module, instance, and entity names are between 5 and 50 characters long.

cso.ShowPassingRules.enable = false;
cso.LineLength.length = 80;
cso.ModuleInstanceEntityNameLength.length = [5 50];

Generate HDL code for your design

Generate HDL code and check it according to the customized HDL coding standard rules. The DUT subsystem is symmetric_fir.

makehdl('sfir_fixed/symmetric_fir','HDLCodingStandard','Industry',...
        'HDLCodingStandardCustomizations',cso, 'TargetDirectory', 'C:/coding_standard/hdlsrc')
