4.2.3.1. Output Path Data Alignment
The data_from_core and oe_from_core signals are arranged in time slices, which are broken down into the individual pins in the group. The first time slice is on the LSBs of the buses, which matches the Intel FPGA PHY interface (AFI) bus ordering of the External Memory Interfaces IP.
Example of time slices with individual pins correlation:
{time(n),time(n-1),time(n-2),... time(0)}
Where time0 = {pin(n),pin(n-1),pin(n-2),...pin0}
