EU Chips Act — SemiWise

Professor Asen Asenov has been a professor at the University of Glasgow's Department of Electrical Engineering for 32 years. He has a strong background in the semiconductor industry, with 42 years of industry experience. In 2010, he founded a successful startup called 'Gold Standard Simulations' (GSS), which focused on advanced CMOS simulation tools. GSS was later acquired by Synopsys in 2016, leading to the establishment of SemiWise in 2017. SemiWise specializes in areas like low-power CMOS modeling and simulation, providing semiconductor IP, device design consulting, software solutions, and training courses. Additionally, Prof. Asenov is involved in UK chip initiatives and advises the Bulgarian government on the EU (European) Chips Act. IDTechEx interviewed Prof. Asenov, discussing the EU Chips Act and the competition in the semiconductor industry in July 2023.
