data_sink_qdac HDL Device Worker

HDL device worker implementation providing common functionality to all DAC device types.

Detail

Be sure to check the samp_count_before_first_underrun and num_underruns component properties at the end of an application run because they are not stable until then. The worker does not use clock domain crossing (cdc) HDL primitive library circuits for these properties because it takes advantage of the fact that they will have a stable value by the time the OpenCPI control plane reads them at the end of an application run.
