hdlcoder.CodingStandard
Create HDL coding standard customization object
Description
creates
an HDL coding standard customization object that you can use to customize
the rules and the appearance of the coding standard report.cso
= hdlcoder.CodingStandard(standardName
)
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
Customize Coding Standard Rules for MATLAB to HDL Workflow
Create an HDL Coding Standard Customization Object
Create a coding standard customization object cso
.
cso = hdlcoder.CodingStandard('Industry');
Customize the Coding Standard Options
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 HDL Codegen Configuration and Coding Standard Customization Object
hdlcfg = coder.config('hdl');
Specify the coding standard and coding standard customization object.
hdlcfg.HDLCodingStandard = 'Industry'; hdlcfg.HDLCodingStandardCustomizations = cso; hdlcfg.TreatRealsInGeneratedCodeAs = 'None';
Generate HDL Code and Test Bench
Specify your test bench function name. In this example, the design function is mlhdlc_dti.m
and the test bench function is mlhdlc_dti_tb.m
.
hdlcfg.TestBenchName = 'mlhdlc_dti_tb';
Generate HDL code for the design and check the code according to the customized HDL coding standard rules.
codegen -config hdlcfg mlhdlc_dti

Customize coding standard rules for Simulink to HDL workflow
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')
