Verification planning
Turn requirements and architectural risks into features, scenarios, assertions, coverage goals, and ownership.

ASIC Design Verification Guide
Design verification builds evidence that an implementation matches its specification across normal operation, corner cases, and failure conditions. The strongest environments connect every stimulus, checker, assertion, and coverage point to a specific risk.
Plan verification around risk, build reusable checking infrastructure, and know what coverage closure actually means.

What this guide covers
Testbench architecture
Separate stimulus, protocol driving, observation, prediction, and checking so components can be reused and debugged independently.
- UVM agents
- Monitors
- Scoreboards and reference models
Stimulus and constraints
Generate legal, meaningful traffic that reaches boundaries without hiding intent inside opaque randomization.
- Constrained random
- Sequences
- Scenario control
Assertions and formal verification
State temporal contracts directly and use proofs where simulation would struggle to cover every relevant trace.
- SVA
- Assumptions and properties
- Bounded and unbounded proofs
Coverage and regression closure
Measure what was exercised, understand what was checked, triage failures, and close meaningful gaps rather than chasing percentages.
- Functional coverage
- Code coverage
- Regression triage
Apply the concepts
Move from reading to reasoning.
Use the question bank to explain assumptions, debug failures, and validate tradeoffs in the language interviewers expect.
