The synchronization interface is a single bidirectional line. Output for Master, input for Slave.
The sync_period value is relative to frame length and the digital interface clock. The actual synchronization
period will be: sync_period * frame_length * fb_clock_cycle
The memory mapped AXI interfaces for the AXI-DMAC are uni-directional.
Which means they are either write-only or read-only. Unfortunately the
Altera tools can't handle this, so we had to add dummy signals for the
other direction.
The Xilinx tools on the other hand handle uni-directional AXI interfaces
and in fact IPI can do a better job and use less resources when creating
the AXI interconnects when it knows that the interface is uni-directional.
So always disable the dummy ports for the IPI package.

For some reason, if a core has an AXI and an AXI Stream interface too, the tool sets the AXI interface's ASSOCIATED_RESET parameter to the AXI Stream interface's reset.
This cause an unconnected AXI reset port in the block design. This 'set_property' command intended to overwrite this automated setup.
