10 TECHNICAL ARTICLES
Practical notes on verification, formal methods, and design.
Original technical guidance grounded in published standards and primary references. No invented project outcomes or anonymous success metrics.
UVM testbench architecture that remains maintainable.
A practical separation of stimulus, protocol observation, prediction, checking, configuration, and coverage.
SystemVerilog assertions that scale beyond block level.
Write properties around sampled intent, explicit reset semantics, reusable interfaces, and actionable failures.
Choosing a useful scope for formal verification.
Select bounded, control-oriented questions with clear invariants instead of treating formal as a universal replacement for simulation.
Formal assumptions, vacuity, and proof coverage.
A green result is meaningful only when the environment is legal, reachable behavior remains possible, and obligations actually trigger.
Formal convergence is an engineering problem.
Diagnose depth, state, arithmetic, memories, and property structure before reaching for arbitrary proof limits.
Clock-domain crossing verification beyond structural checks.
Combine structural analysis, protocol properties, reset review, and simulation stress to verify synchronizers and data-transfer schemes.
Verification strategy for a custom RISC-V extension.
Verify encoding legality, architectural state, privilege interactions, exceptions, and microarchitectural behavior against a precise extension specification.
Coverage closure as a risk model, not a percentage.
Connect each coverage target to a requirement, a checker, a review decision, and a documented reason for exclusion.
Design for verifiability before the testbench exists.
Make intent observable and controllable through explicit state, stable interfaces, deterministic reset, assertions, and bounded structures.
Bring us your hardest verification problem.
A focused specialist or a defined work package — scope, responsibilities, milestones, and evidence are agreed for each engagement.
