LogiCORE IP Digital Pre-Distortion (DPD) v6.0 - The requirement of having the DCL state machine reset before starting the DCL process after boot up


The DCL state machine has no defined default state which may cause a poor initial update. The poor update can prevent the DPD core from achieving good correction performance.

Note: This applies to all versions of the DPD core.


Send either the SET_DCL_PARAMETERS or RESET_DCL commands before issuing any of the RUN_DCL commands (RUN_DCL, RUN_DCL_WITH_ACCEL_QMC, or RUN_DCL_WITH_QMC). Either of these commands will reset to the state machine within the DCL routine.
