Design of SPI Slave Circuit

Serial Peripheral Interface(SPI) is a full-duplex synchronous serial bus,which is presented by Motorola Company.Microcontroller can communicate with other microcontrollers or peripheral devices by this interface.The characteristic of SPI is less-wired and more efficient in the communication,which make SPI popular in integrated circuit designs.The basic conception of Intellectual Property(IP) is described in this paper,based on the application specified slave device of SPI.This paper also introduces the design flow of the integrated circuit,included requirement analyze,logic design,simulation and physical implementation,and the general method of low power design and reliability verification.
