UVM Verification
to Coverage Closure

Constrained-random UVM testbenches, functional coverage planning, and formal verification — designed to close coverage on your schedule, not after it.

Overview

Verification That Finds Bugs, Not Just Runs Simulations

What is UVM Verification? Before a chip design is sent to the factory, it must be tested thoroughly in simulation. UVM (Universal Verification Methodology) is the industry-standard framework for building automated test environments that check whether a chip's logic is correct — catching design bugs before manufacturing, when fixes are still inexpensive.

Quantova builds UVM verification environments from scratch or extends existing ones — focused on finding functional bugs, not generating simulation logs. We define coverage metrics before writing a stimulus line.

Every testbench includes a coverage plan, directed test cases, constrained-random stimulus, and a coverage closure strategy with regular sign-off milestones.

What We Deliver

Verification Capabilities

UVM Testbench Development

Complete UVM environment: agents, scoreboards, coverage models, and sequence libraries built for your DUT.

Coverage Closure

Functional coverage plan, code coverage setup, and closure-driven test development until sign-off thresholds are met.

Formal Verification

Property writing in SVA, formal proof of specific functional properties, and connectivity checks.

Regression Management

Nightly regression setup, failure triage, and coverage reporting dashboards for your design team.

Deliverables

What You Receive

  • UVM testbench source code (agents, scoreboards, sequences, coverage models)
  • Verification plan document with coverage goals and test strategy
  • Coverage closure report (code coverage and functional coverage)
  • Regression summary with pass/fail log for all test cases
  • Formal property set in SVA (if formal verification is included)
  • Bug report with root-cause analysis for all design issues found
DUT-agnostic: We can work with your existing RTL or alongside a parallel RTL development effort using a model or spec-based reference.

FAQs

Common Questions

Yes. We can audit your existing environment, identify gaps, and extend it rather than starting from scratch — provided the existing code meets minimum quality standards.

We target whatever your project sign-off criteria specify. Typically 95%+ code coverage and 90%+ functional coverage, with documented exceptions.

Get Your DUT Verified

Share your RTL and verification plan. We will review the scope and propose a verification closure timeline.
