Crate marlin_verilator 

This module implements the Verilator runtime for instantiating hardware modules. The Marlin Verilator runtime supports DPI, VCDs, and dynamic models in addition to standard models.

For an example of how to use this runtime to add support for your own custom HDL, see SpadeRuntime (under the “language-support/spade/” directory), which just wraps VerilatorRuntime.

Re-exports

pub use dynamic::AsDynamicVerilatedModel;

Modules

dpi

See the #[verilog::dpi] macro for details.

dynamic

Support for dynamic models.

ffi_names

Ensures all FFI function references are consistent.

nocapture

types

Verilator-defined types for C FFI.

vcd

Macros

eprintln_nocapture

Structs

VerilatedModelConfig

Configuration for a particular [VerilatedModel].

VerilatorRuntime

Runtime for (System)Verilog code.

VerilatorRuntimeOptions

Optional configuration for creating a VerilatorRuntime. Usually, you can just use VerilatorRuntimeOptions::default().

WideIn

LENGTH is compute_wdata_length_from_width_not_msb(HIGH + 1) where HIGH is the most significant bit.

WideOut

See WideIn.

Enums

CxxStandard

Based off of the C++ standards supported by GCC as of June 6th, 2025.

Traits

AsVerilatedModel

You should not implement this trait manually. Instead, use a procedural macro like #[verilog(...)] to derive it for you.
