Deep expertise in Universal Verification Methodology (IEEE 1800.2) for FPGA verification

General

What this skill does


# UVM Methodology Skill

## Overview

Expert skill for Universal Verification Methodology (UVM) development following IEEE 1800.2 standards for comprehensive FPGA verification.

## Capabilities

- Generate UVM agent architecture (driver, monitor, sequencer)
- Create UVM environments and scoreboards
- Implement uvm_sequence and virtual sequences
- Configure UVM factory and config_db
- Implement functional coverage with covergroups
- Design UVM register models (RAL)
- Apply UVM phasing and objections correctly
- Debug UVM testbenches effectively

## Target Processes

- uvm-testbench.js
- constrained-random-verification.js
- testbench-development.js

## Usage Guidelines

### Agent Architecture
- **Driver**: Converts sequence items to pin-level activity
- **Monitor**: Observes DUT interface and creates transactions
- **Sequencer**: Routes sequence items to driver
- **Agent**: Contains driver, monitor, sequencer; configurable active/passive

### Environment Structure
- Top-level environment contains agents and scoreboard
- Scoreboard performs reference model comparison
- Config objects distribute configuration
- Virtual sequencer coordinates multiple agents

### Sequence Development
- Extend from uvm_sequence#(item_type)
- Use `start_item()` / `finish_item()` paradigm
- Create layered sequences for complex scenarios
- Use virtual sequences for multi-agent coordination

### Coverage Strategy
- Embed covergroups in monitors
- Sample on transaction completion
- Cross functional coverage points
- Track coverage closure progress

### Best Practices
- Use factory for all component creation
- Configure via config_db, not constructors
- Raise/drop objections properly
- Use UVM reporting macros consistently

## Dependencies

- UVM 1.2 or UVM IEEE 1800.2 library
- SystemVerilog expertise
- Verification methodology knowledge

let-fate-decide

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
