The SP7021 SOC platform self-test experiment is mainly used to test the reliability of the SOC platform connection. The design of the FBIO is placed on the FPGA daughter board. The Plus1 chip reads and writes the FBIO to realize the reliability test of the connection between the Plus1 chip and the FPGA daughter board pin .

1.1 SP7021 SOC platform self-test design experiment project hardware platform implementation

The SP7021 SOC platform self-test experiment only needs to connect the axi_m and axi_s 64bit bus interfaces of the FBIO Wrapper together, and do the corresponding address mapping. That is, the access to the FBIO start address 0x70000000 is mapped to the access to the DRAM start address 0x00000000 in the Plus1 chip ;As shown below:
