LSI Circuit Design/Semiconductor Design

We are responding to the increasingly sophisticated, diverse, and complex demands of LSI/semiconductor design through a comprehensive design system that integrates circuit design and layout design.
SANEI HYTECHS has a track record as a specialized LSI/semiconductor design company since the dawn of the LSI industry. Today, we provide a comprehensive design system that integrates three businesses: analog circuit design, logic/digital circuit design, and layout design, all working together in collaboration. Our digital and analog circuit designers work together, utilizing tools such as MATLAB/Simulink to design the system as a whole.

Furthermore, our layout designers work in close collaboration with analog circuit designers to pursue the reduction of layout area to the limit while realizing circuit characteristics. LSI design requires not only performance but also the ability to meet requirements such as miniaturization and energy efficiency. We strive to achieve the optimal balance between circuit design and layout design, leveraging the latest tools and technologies available.

We understand that the field of LSI design and semiconductor design will continue to advance, diversify, and become increasingly complex in the future. Therefore, we remain at the forefront of technological trends, conducting research and development to swiftly and appropriately respond to our customers' needs.

We believe in the importance of fostering a partnership with our clients, and our mission is to contribute to their success. Our ever-evolving engineering business aims to be a vital force in supporting the advancements of next-generation technologies and becoming an indispensable presence in shaping the future society.

SANEI HYTECHS has a team of designers who can handle both design and specification considerations. They create design specifications based on the required specifications for LSI development. To achieve the operation and characteristics of the requested system LSI, they design the architecture using tools such as MATLAB/Simulink and functional model verilogA. In mixed-signal LSI development, analog and digital circuits are appropriately integrated and separated during this stage. Our company's distinctive feature is having architecture designers who can efficiently streamline the system LSI design process using a top-down approach.
