3.2.4.1. FPGA Writing to Memory

The following topics explore the differences between populating slot 1 and slot 2 of the dual‑DIMM memory interface.

Previous topics focused on the dual-DIMM memory interface where slot 1 is populated resulting in the memory being located closer to the FPGA. When slot 2 is populated, the memory is located further away from the FPGA, resulting in additional trace length that potentially affects the signal quality seen by the memory. The following topics explore the differences between populating slot 1 and slot 2 of the dual‑DIMM memory interface.
