Unconstrained signal or variable of integer type

In VHDL, it is good practice to constrain integer types (or types derived from integer types) when they are used for signals. Doing so will allow the synthesis tool to optimize the number of bits used for this signal. If this rule is enabled, Sigasi will report all unconstrained integer types used for signals.

VHDL
...
signal sig_a : integer;
signal sig_b : integer range 0 to 100;
...

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
```
{
    "vhdl.rules.236.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
```
236/severity/${path}={error|warning|info|ignore}
```
