126.96.36.199. Device Power Cycling and Reconfiguration
|1||Consider designing your system to support power cycling the device to ensure error recovery under all reconfiguration circumstances.|
Unlike previous FPGA devices that used state machines for controlling configuration, the Intel® Agilex™ devices use the triple-redundant processors in the SDM to control configuration. To ensure error recovery under all reconfiguration circumstances, Intel® recommends that you design your system to support power cycling the device if needed. In almost all use cases, asserting nCONFIG provides adequate error recovery, however, a power cycle may be required in rare instances. A power cycle completely re-initializes the device, samples MSEL, reads the fuses and runs the SDM BootROM code. Device power up and power down sequences must be followed during the power cycle.
