Address Look-Up

You must know the lane addresses and the pin placement to address an interface correctly. Because these

values are placement dependent, these values will be different before and after placement. The Altera

PHYLite for Parallel Interfaces IP core is generated as if the IP core is the only IP core in a column, with

lane addresses starting from 0. If the IP core is placed in a column containing Arria 10 External Memory

Interfaces or Altera PHYLite for Parallel Interfaces IP cores (with dynamic reconfiguration), then the

addressing of the I/O lanes in the interfaces must be modified to avoid conflicts. A pin can also be moved

into any lane within a group. In general, even if the Altera PHYLite for Parallel Interfaces IP core interface

is the only IP in the column, the Fitter will still modify the addresses.
