Verilog inputs

Although the input direction is taken by default, it is preferable to explicitly specify the direction to improve readability and make the code self-documenting.

VERILOG
module bad_example;

	function int my_func(int a, b);          // bad: direction of a and b omitted
		return a+b;
	endfunction
	
	task my_task(int a, b);                 // bad: direction of a and b omitted
	begin
		$display(a);
		$display(b);
	end
	endtask
	
endmodule

VERILOG
module good_example;

	function int my_func(input int a, b);   // good: direction of a and b specified
		return a+b;
	endfunction
	
	task my_task(input int a, b);          // good: direction of a and b specified
	begin
		$display(a);
		$display(b);
	end
	endtask
	
endmodule

Rule configuration

This rule can be disabled for your project, or its severity and parameters can be modified in the project linting settings. Alternatively, it can be manually configured using one of the following templates, depending on the type of project you use.

For Modular Projects, add these entries to your project's .sigasi/settings.json settings file. To scope the settings to a specific folder or file instead of the whole project, place them inside an @override block; to scope them to a specific target, place them inside a @targets block.
JSONC
```
{
    "verilog.rules.14.severity": "{ERROR|WARNING|INFO|IGNORE}"
}
```
For Classic Projects, add the VHDL lines to .settings/com.sigasi.hdt.vhdl.linting.prefs and the Verilog/SystemVerilog lines to .settings/com.sigasi.hdt.verilog.linting.prefs:
PREFS
```
14/severity/${path}={error|warning|info|ignore}
```
