We know that the straightforward configuration file for the Vitis compiler linker did not meet timing. This was because this design is a high resource utilization design, running at a high frequency clock rate (400 MHz). The Vivado tool cannot perform timing closure without user intervention. This is solved by adding two axi4s-register slice IPs between the PL kernels and the AI Engine, updating the connections in the configuration file, and applying timing closure strategies during placement and routing.
