The SPI protocol allows for four different clocking types, based on the polarity and phase of the SCK signal.
Some examples of such low-cost serial buses include RS-232, SPI, I☬, UNI/O, 1-Wire and PCI Express. Now let’s see in little more detailed level like how it is working in hardware level. The HTD, HME and HCE pressure sensors are configured to comply with the SPI bus protocol. the internal bootloader via the UART protocol. Hope you got the basic idea of an SPI bus. It demonstrates that Model-Based Design is a very good fit for protocol implementation. SPI slave devices Verification of the core is done by simulation in ModelSim®. As the complexity of the circuit is numerous so there is need of verification methodology to quench the product failure. Spi protocol verification Santhoshkrishna IJSETR, 2015 Design and functional verification of a SPI master slave core using UVM-IJSETR.
