Front-end and back-end design of integrated circuits

Answer the last question first. Integrated circuit design is to design the integrated circuit (chip) itself; The system design related to MCU or CPU uses the existing chip design system.

The design of integrated circuits is roughly divided into two steps: front-end and back-end. Front-end design, mostly design digital logic circuits to achieve predetermined functions; The back-end design is to wire the designed logic circuit in a device layer and multiple metal layers. The design results are submitted to the factory for production.

Both front-end design and back-end design of integrated circuits need special training, and it is impossible to teach yourself with special design tools.
