MPSoC to Versal Resets Comparison
The PMC reset structure is expanded to include more device-level controls with features to support new packaging technologies.
The device has one dedicated reset pin, POR_B. This pin asserts the external power-on reset, External_POR. The Versal device does not include the AMD Zynq™ UltraScale+™ MPSoC PS_SRST_B reset pin.
The programming model includes device-level system resets for the reset controllers that are similar to the Zynq UltraScale+ MPSoC.
