Description
According to the Intel® Agilex™ Device Data Sheet, the minimum reset pulse width for the HPS_COLD_nRESET signal is 3 msec (Trst0). If a pulse width of less than 3 msec occurs on this pin, an unintentional reset may occur. The HPS system may inadvertently detect pulses as short as approximately 0.3 msec in width.
Resolution
To work around this issue, implement an external hardware debounce circuitry that will hold the HPS_COLD_nRESET signal asserted for a minimum of 3 msec.
