Design Verification
UVM environments, coverage-driven closure and the evidence that a block actually works before it is implemented.
What we deliver
We build and run the verification environment that proves your RTL meets its specification — testbench architecture, stimulus, checkers and coverage model — and we close coverage against a written verification plan rather than against a test count.
Scope of work
Verification planning
A verification plan derived from the specification: features, the checks that prove them, the coverage that measures them, and the signoff criteria — agreed before the testbench is written.
Environment development
UVM testbench architecture, agents, sequences, scoreboards and reference models, standard bus VIP integration, and regression infrastructure with result triage.
Coverage closure
Functional and code coverage modelling, constrained-random and directed stimulus, coverage-hole analysis, and closure reporting traceable back to the verification plan.
Methods we use
Simulation-based
UVM and SystemVerilog constrained-random verification, directed tests for corner cases, and nightly regression with automated failure triage.
Assertion-based
SVA properties for interface protocols and internal invariants, used both as simulation checkers and as formal targets.
Formal
Formal property verification for control logic, connectivity and register-map checking, and targeted proofs where constrained-random coverage is impractical.
Gate-level
Gate-level simulation with timing, X-propagation and reset sequence validation, and post-DFT netlist sanity runs.
Typical deliverables
- Verification plan mapped to the design specification
- UVM testbench source and reusable components
- Test suite with regression scripts
- Functional and code coverage reports against signoff criteria
- Assertion set and formal proof results where applicable
- Bug list with reproduction cases and status
- Verification signoff summary and residual-risk statement
Verification behind schedule?
Tell us the block, the interfaces and the coverage state. We will scope what it takes to reach signoff.
