Hi @Suprith

The reset button on the Arty Z7 is not directly connected to the FPGA PL. Reviewing the schematic, the reset button, connected to the PS_RST net, triggers the PS side of the chip to reset and drives a reset on the CK_RST net, which is connected to the shield header reset pin. CK_RST is also connected to PS MIO12, however, this would not allow the PS to read a reset button press, since the upstream PS_RST will be applied.

Reset signals within the FPGA can alternatively be driven by resets associated with the FCLKs.
