What is the difference between Functional Coverage and Code Coverage?
Code Coverage is a simulator-extracted metric checking which lines, branches, or toggles of the RTL code were executed. Functional Coverage is user-defined metric verifying whether all design features, state combinations, and protocols defined in the specification were tested.
Introduction to Functional Coverage vs Code Coverage in VLSI
Understanding the details of Functional Coverage vs Code Coverage in VLSI is essential for front-end verification, DFT testing, or backend timing closure in modern sub-micron silicon processes.
This daily knowledge byte offers concise definitions, architectural outlines, and practical design solutions to support your engineering career.
Core Technical Fact Card
• Topic: Functional Coverage vs Code Coverage in VLSI
• Key Objective: Elevate chip reliability, speed performance, and yield parameters.
• Tools Associated: Synopsys, Cadence, Mentor Graphics EDA suites.
Detailed Technical Principles
In high-speed semiconductor integration, engineering success relies on modeling physical variations precisely. Managing setup margin constraints, logical coverage tracking, low-power constraints, or wafer testability allows modern chip designs to satisfy strict market requirements.
Why This Matters for Placements
