Huangyan is famous and known as "the godfather of EDA". 1982, when he was dismissed or even forced to receive unemployment benefits, Huangyan founded Cadence. Five years later, cadence was officially listed on NASDAQ, and within five or six years of its establishment, it took the lead in the global industry. Later, he founded Pie Design System, Quickturn Design Systems and Siyuan Technology, all of which have achieved good results in the industry and successfully listed.

Huang Yan turned to the microphone again because he thought that "voice control application" would be the next trend product. Yan Huang thinks that handheld consumer products with voice control function will be the future trend. Fudi's team tried to improve the defect that microphones need to be in quiet places to receive sound well, so that people can meet the needs of food, clothing, housing and transportation with one mouth in various environments.

Unemployed for more than three months, Huang Yan is busier than when she was an engineer at National Semiconductor and Gude Semiconductor. He has read Sun Tzu's Art of War, and even analyzed Yihua's entrepreneurial niche with "Tao, Heaven, Earth, General and Law". At that time, he thought that the development of semiconductors confirmed Moore's law and the industrial growth rate would advance by leaps and bounds. "Yihua has a favorable geographical location, legal system and R&D talents in Silicon Valley, and its future is limitless."

Huangyan successfully developed a design software called "Vampire". After one year, the performance reached 40 million dollars, and the turnover soared. Vampires have also maintained a leading position in EDA industry for nearly ten years.
