Sigasi Studio for VS Code Editor

Semantic Highlighting

The Sigasi extension supports semantic highlighting, however, some VS Code themes might not support it yet. Be sure to use the default VS Code themes if you’re missing this feature.

• In a theme that supports semantic highlighting, you’ll see that e.g. port, signal, and type names have a color that is different from the language keywords.
  

  

• In a theme that does not support semantic highlighting, names like those of a port, signal, or type will have the default text color.

  

User-Defined Code Snippets

VS Code supports user-defined code snippets as explained here. To add snippets yourself, follow the steps below.

• Open the Command Palette (Ctrl+Shift+P) and type Snippets
• Select Snippets: Configure User Snippets
• Type vhdl or systemverilog to open the corresponding JSON file where you can add your snippet like the examples below.

VHDL Snippet Example

{
    // Place your snippets for VHDL here.
    "package declaration": {
        "prefix": "package",
        "body": [
            "package ${1:name} is",
            "\t$0",
            "end package $1;"
        ],
        "description": "Insert package declaration"
    }
}

SystemVerilog Snippet Example

{
    // Place your snippets for Verilog and SystemVerilog here.
    "always posedge clk": {
        "prefix": "always",
        "body": [
            "always @(posedge ${1:clk}) begin",
            "\t$0",
            "end"
        ],
        "description": "Insert an always block with posedge clock"
    }
}

Sticky Scroll

You can use the sticky scroll to navigate through your HDL code more easily. This setting can be enabled with the key editor.stickyScroll.enabled
