Digital integrated circuit design continues to grow in scale and complexity, making functional verification one of the most important skills for modern hardware engineers. This course provides a complete and structured path for learning how to verify digital designs with confidence, efficiency, and clarity. It introduces the fundamental concepts that shape the verification workflow, then expands into advanced methodologies used across the industry to build reliable verification environments. The focus is not only on learning techniques, but also on understanding why these techniques matter, how they fit together, and how they elevate the quality of a design. The course begins by exploring the overall flow of functional verification. Students learn how verification develops alongside design, how goals are defined, and how a verification strategy evolves as the project becomes more complex. Concepts such as constrained random testing, automation, behavioral checking, and coverage-based progress measurement are introduced to show how modern verification frameworks outperform traditional directed testing. The emphasis is on building a mindset that sees verification as a measurable, st...
