-- Purpose: DDR3 memory access component for Stratix IV.
-- Description:
-- Remarks:
-- . The local_init_done goes high some time after power up. It could have been
-- AND-ed with ctlr_miso.waitrequest_n. However the timing closure for
-- ctlr_miso.waitrequest_n can be critical, so therefore it is better not
-- to combinatorially load it with the AND local_init_done. Instead a
-- ctlr_miso.done field was added and used to pass on local_init_done.
-- Declare IP libraries to ensure default binding in simulation. The IP library clause is ignored by synthesis.
