PS-PL Signals and Interfaces

The PS and PL can be tightly coupled in a heterogeneous processing system using the many signals and interfaces between the LPD and FPD in the PS and the functionality configured in the PL. The PL can also be independently isolated from the LPD and FPD regions using isolation walls. The PS-PL signals and interfaces also include other functions to configure and control the device. The PS-PL signals and interfaces include these groups:

•PS-PL Voltage Level Shifters

•Processor communications

•System error signals

•MIO-EMIO signals and interfaces

•Miscellaneous signals and interfaces

•Dedicated stream interfaces

•DisplayPort media interfaces

•Clock signals

•Timer signals

•System debug signals and interfaces

The PS-PL signal and interface names are listed in the Zynq UltraScale+ MPSoC Processing System LogiCORE IP Product Guide (PG201) [Ref 27].
