This paper explores the intricate methodologies for functional verification of mixed-signal designs, crucial in ensuring the correct operation of increasingly complex integrated circuits. These designs, combining analog and digital components, present unique verification challenges due to the interplay between continuous-time and discrete-time signals. Traditional digital verification techniques fall short in addressing these complexities, demanding specialized approaches. This paper provides a comprehensive overview of state-of-the-art methodologies for verifying mixed-signal designs. It explores challenges and solutions in detail, analyzing critical aspects like advanced simulation techniques, formal verification methods, and complexity reduction strategies. The paper also highlights the importance of metric-driven verification and examines emerging trends like emulation, FPGA prototyping, and AI/ML integration. This knowledge equips engineers to ensure robust and reliable mixed-signal designs in today's complex technological landscape.
