Projektgeschichte

The public repository was created in 2019. The README describes UHDM's purpose as auto-generating a concrete C++ implementation of the SystemVerilog object model, a standard VPI facade, serialization and deserialization, visitor and listener traversal code, and elaboration logic.

UHDM's model is expressed in YAML files that follow the object-model portion of the SystemVerilog 2017 standard. The generated model can be populated by parsers such as Surelog or Verible and consumed by downstream tools such as Yosys and Verilator.

Release metadata shows v0.9.2 in 2022, v1.84 in 2024, and v1.85/v1.86 in 2025, reflecting its role as an evolving infrastructure library rather than a one-off command.

Adoptionsgeschichte

UHDM adoption is strongest in the open-source EDA and hardware-description-language ecosystem. Its README explicitly names Surelog and Verible as producers and Yosys and Verilator as consumers, placing it in the interchange layer between SystemVerilog front ends and analysis, synthesis, or simulation tools.

The supplied package data records UHDM in Homebrew and Nix. For package users, that makes a complex C++/Cap'n Proto/SystemVerilog infrastructure component installable without building the entire open-source EDA stack by hand.

Wie es verwendet wird

Developers use UHDM as a library and toolset for creating, serializing, inspecting, elaborating, and traversing SystemVerilog designs. The Homebrew package exposes utilities such as uhdm-dump, uhdm-cmp, uhdm-hier, and uhdm-lint.

The README describes uhdm-dump as a way to produce a human-readable view of a serialized UHDM design, and it describes listener and visitor patterns for client applications that need to traverse designs while the data model evolves.

Warum Paket-Nerds sich dafür interessieren

UHDM is significant to package maintainers because it is plumbing for open-source hardware tooling. It pulls together generated C++ code, serialization, VPI compatibility, optional Python bindings, and downstream EDA consumers, so a working package can unblock multiple SystemVerilog workflows.

In the package-nerd niche, UHDM represents the move from monolithic EDA tools toward separately packaged interchange libraries that distributions can compose into parsers, linters, synthesizers, and simulators.
