Verification Built for First-Pass Silicon
Bugs can be found long before tape-out. It takes an architecture, a coverage discipline, and an automation habit.
Where Verification Breaks Down
Verification consumes the largest share of a SoC schedule, yet it is the hardest part to estimate. A respin costs a mask set and a market window. Teams often discover late that coverage numbers looked healthy while entire scenarios were never exercised.
The symptoms are familiar to any verification engineer. Testbenches built for one block resist reuse in the next. Coverage closure stalls at the last few percent because the remaining bins are unreachable and nobody has proven it. Regressions take long enough that engineers stop running the full suite, and failures accumulate until a debug session turns into archaeology.
Two Ways to Verify
Conventional Approach
- Testbench built per block, hard to carry to the next level
- Coverage measured after the tests exist
- One regression suite, run manually before milestones
- Results reviewed run by run, by hand
MetaEncore Approach
- Layered architecture reused across block, subsystem, and SoC levels
- Coverage model written alongside the verification plan
- Regression runs in tiers, from fast checks to full runs
- Results collected automatically, coverage merged across runs
What We Deliver
UVM Testbench Development
Layered environments, protocol agents, and reusable verification components built to serve block, subsystem, and SoC levels from one architecture.
Pre-Silicon Validation
System integration checks, performance and power scenarios, and early software bring-up, linked together so that what you tape out is verified silicon.
Verification Infrastructure
Regression automation, coverage tracking, and automated result collection that keep the verification loop short enough for engineers to actually use it.
How We Work
Testbench Architecture
We build in layers. A reusable agent per protocol, a scoreboard that checks at transaction level, and a test layer kept deliberately thin: each test extends a common base and adds only what is specific to it. Configuration lives in objects rather than in code, so the same environment serves block, subsystem, and SoC levels without a rewrite. Sequences are written to compose, so a new scenario is usually a combination of existing pieces rather than new code.
Coverage Strategy
We work from the verification plan rather than from the simulator, mapping features to functional coverage points as the plan takes shape, so that closure measures the plan and not the testbench. Constrained-random stimulus explores the broad space, directed tests reach corners that randomization is unlikely to find, and unreachable bins are proven and waived deliberately rather than quietly ignored.
Tiered Regression
Regression runs in tiers rather than as a single job. Lighter suites give a fast signal while work is in progress, broader ones run on a longer cadence, and the full regression keeps its own schedule: on a real SoC a complete pass can take days, so treating every change as a trigger would only guarantee that nobody waits for the result. Each tier trades breadth for turnaround, and the tiers are sized to the project rather than to a fixed template.
Results are collected automatically and coverage is merged across runs, so there is one place to see where the design actually stands rather than a folder of logs to reconcile by hand.
