Note: The RFSoC devices are reliable as
long as the Recommended Operating conditions specified in the
Zynq
UltraScale+ RFSoC Data Sheet: DC and AC Switching
Characteristics (DS926) are not violated. In case the
power distribution network can exhibit voltage overshoot exceeding the maximum operating
condition during bitstream reconfiguration, then the below procedure is recommended to
prevent any impact on the lifetime reliability of the device.
To load a new bitstream or reload the current bitstream into the AMD Zynq™ UltraScale+™ RFSoC when there are one or more tiles in operation then the following steps must be followed to ensure safe operation. Failing to follow these steps during a reconfiguration event can potentially impact lifetime reliability of the part.
- Mute the analog front end to avoid TX and RX signaling.
- Individually shut down all RF-ADC and
RF-DAC tiles used using the
XRFDC_ShutdownAPI command or the Power-Down Tile registers. - Load the new bitstream or reload the existing bitstream.
- After configuration, the tiles will start up in the correct sequence by the power-up state machine in the IP.
