7.3.3.6. User Mode

You can enable the optional INIT_DONE pin to monitor the initialization stage. After the INIT_DONE pin is pulled high, initialization completes and your design starts executing. The user I/O pins then function as specified by your design.

During device initialization stage, the FPGA registers, core logic, and I/O are not released from reset at the same time. The increase in clock frequency, device size, and design complexity require a reset strategy that considers the differences in the release from reset. Altera recommends that you use the following implementations to reset your design properly and until the device has fully entered user mode:

  • Hold the entire design in reset for a period of time by following the CONF_DONE high to user mode (tCD2UM) or CONF_DONE high to user mode with CLKUSR option turned on (tCD2UMC) specifications as defined in the Arria® 10 Device Datasheet before starting any operation after the device enters into user mode. For example, the tCD2UM range for Arria® 10 device is between 175 us to 830 us.
  • Use an internal init_done signal to hold the reset of your core registers, core logic, and I/O registers until the device has fully entered user mode. The internal init_done signal is high (enabled) until the entire device enters user mode.

);
  • If you have an external device that reacts based on an Altera FPGA output pin, perform the following steps to avoid false reaction:
    • Ensure that the external device ignores the state of the FPGA output pin until the external INIT_DONE pin goes high. Refer to the tCD2UM or tCD2UMC specifications in the Arria® 10 Device Datasheet for more information.
    • Keep the input state to the external device constant by using the external logic until the external INIT_DONE pin goes high.
