Reset process.

The nRST signal active low reset input, forces PS_POR_B to apply a master reset of the entire Zynq. This reset could be manually done by pressing a switch. This signal could be also reached by a B2B large connector.

This nRST signal (active low) is also held until all FPGA power supplies set their Power Good signals.

Furthermore, if the FPGA core voltage drops under 0.84V or the 3.3V power supply drops to 2.94V or less, this nRST signal is also activated by the Voltage Monitor.

See more about the Power-on Reset (PS_POR_B) signal in the “Zynq-7000 SoC Technical Reference Manual” (“UG585”).
