Table 1. Status Ports
Port Name I/O Clock Description
events[6:0] O s_axis_aclk The core generates the event signals. The format is described in the following table.
Table 2. Event Bits
Event name Bit Description
event_config_error 0 Received an invalid configuration packet.
event_maxpt_ignored 1 The core was requested to reduce the maximum point size while a block larger than the new maximum point size was still being processed. The request was ignored and the next operation was started using the previous maximum point size setting.
event_ctrl_underrun 2 A new data frame began on the input interface, but there was no control packet available in control FIFO to determine the processing parameters.
event_tlast_unexpected 3 The core saw the 'Last' flow control signal on the data input interface at an unexpected time.
event_tlast_missing 4 The core did not see the 'Last' flow control signal on the data input interface at the expected time.
event_ecc_event 5 An ECC event was detected when reading from one of the DFE FFT primitives' internal RAM instances. This event is flagged for 1-bit (recoverable) and multi-bit (unrecoverable) ECC events.
event_ecc_nbit_error 6 A multi-bit error (unrecoverable) was detected when reading from one of the internal RAM instances of the DFE FFT primitives.
