Signoff analysis is an important step of the digital IC design, which does the most accurate and complete analysis for the entire chip.The TAI system performs a full range of inspections at this stage, from high-precision numerical calculations to the functions and constraints of the physical chip, quickly applying the experience of senior engineers to chip inspection. The Rigoron team has been engaged in the research and development ofSignoff software for many years, developing a highly accurate and efficient computing engine, accurately locating chip problems, accelerating physical iterations, and escorting the development of ultra-large-scale high-performance SoCs, CPUs, and GPUs.
