I/O pin or open-drain output pin. When this pin is enabled, the low-to-high transition on this pin indicates that the FPGA has entered user mode. If the INIT_DONE output pin is enabled, this pin cannot be used as user I/O after configuration is complete. You can enable this pin in Quartus II by enabling the Enable INIT_DONE output option.
Operating system initialization: When the computer starts, the operating system will perform a series of initialization operations, such as loading drivers, allocating memory, establishing system data structures, etc. The INIT_DONE flag is usually used to indicate that the operating system has been successfully initialized and can start loading user applications and providing services.
Software application initialization: Software applications usually require some initialization work at startup, such as loading configuration files, establishing database connections, setting up runtime environments, etc. The INIT_DONE flag can be used to indicate that the application has completed these initialization steps.
Hardware initialization: In embedded systems, the INIT_DONE flag can be used to indicate that the initialization of the hardware device has been completed. This can include initializing sensors, performing self-test routines, configuring peripherals, etc.
Network communication: In network communication, INIT_DONE can indicate that the network device or connection has been successfully initialized and is ready for data transmission.
