1.2.6. Reset Release Intel® FPGA IP

This IP holds a control circuit in reset until the device has fully entered user mode. The FPGA asserts the INIT_DONE output to signal that the device is in user mode. The Reset Release IP generates an inverted version of the internal INIT_DONE signal to create the nINIT_DONE output that you can use for your design. The nINIT_DONE signal is high until the entire device enters user mode. After nINIT_DONE asserts (low), all logic is in user mode and operates normally. You can use the nINIT_DONE signal in one of the following ways:
  • To gate an external or internal reset.
  • To gate the reset input to I/O PLLs.
  • To gate the write enable of design blocks such as embedded memory blocks, state machines, and shift registers.
  • To synchronously drive register reset input ports in your design.
