Constraining spi interface

WebSPI protocol has earned a solid role in embedded systems whether it is system on chip processors, both with higher end 32-bit processors such as those using ARM, MIC or Power PC and with other microcontrollers such as the AVR, PIC etc. These chips usually include SPI controllers capable of running in either master or slave mode. In-system … WebMy solution: 1)output path: Add LOC constraints to MMCM and BUFG in order to minimum SPI_CLK output delay, then add FROM:TO constraint to data output path, as a result, meeting the setup and hold of SPI flash. 2)input path: Modify coding style in order to make the input registers to be packed into IOB, which save at least 7 ns input delay.
