New Language Features

Support reference to type defiend in existing package via proto package #1691

Proto typedefs are allowed to have their actual types. This allows a type symbol defined in a different package to be imported into the proto package and referenced from other components through it.

package FooPkg {
    struct Foo {
        foo: logic,
    }
}

proto package BarProtoPkg {
    type Foo = FooPkg::Foo;
}

package BarPkg for BarProtoPkg {
    type Foo = FooPkg::Foo;
}

module ModuleA::<PKG: BarProtoPkg> {
    var _foo    : PKG::Foo;
    assign _foo.foo = 0;
}

module ModuleB {
    inst u: ModuleA::<BarPkg>;
}

Add const declarations to StatementBlockItems #1695

const declaration can be used in statement blocks.

function foo () -> u32 {
    const bar: u32 = 2;
    return bar;
}

Support embed declaration in component declaration #1712

embed declaration with sv block can be used in component declaration like module, interface and package.

module ModuleA {
    embed (inline) sv{{{
        initial begin
            $display("hello");
        end
    }}}
}

New Tool Features

Merge Waveform Render into Veryl VS Code Extension #1713

VSCode Extension supports preview of waveform in documentation comments.

Add support for including additional files for tests #1718 #1729

Additional files for test can be specified by include_files. For example, it can be used to specify HEX files which are read by $readmemh.

[test]
include_files = ["test.hex"]

Allow to specify multiple source directories #1747

Multiple source directories can be specified via sources instead of source. source becomes deprecated, and will be removed after a few versions.

[build]
sources = ["rtl", "tb"]
