UVM-based functional verification — testbench architecture, test planning, directed and constrained-random stimulus, functional and code coverage closure, formal assist, and regression sign-off. Use when building a UVM testbench, writing tests, analysing coverage, or managing a verification regression.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill: Functional Verification (UVM) ## Invocation When this skill is loaded and a user presents a verification task, **do not execute stages directly**. Immediately spawn the `digital-chip-design-agents:verification-orchestrator` agent and pass the full user request and any available context to it. The orchestrator enforces the stage sequence, loop-back rules, and sign-off criteria defined below. Use the domain rules in this file only when the orchestrator reads this skill mid-flow for stage-specific guidance, or when the user asks a targeted reference question rather than requesting a full flow execution. ## Pre-run Context Before executing or advising on **any** stage, read the following files if they exist: 1. `memory/verification/knowledge.md` — known failure patterns, successful tool flags, PDK/tool quirks. Incorporate its guidance into every stage decision. If absent, proceed without it. 2. `memory/verification/run_state.md` — current run identity (`run_id`, `design_name`, `tool`, `last_stage`). Use this to resume correctly after interruption. If absent, a new run is starting; the orchestrator will create this file before the first stage. …

How to install
mdr add hdl-tools/digital-chip-design-agents/functional-verification@sha256:58b3397839a56a30The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
