WebI have a design that uses the MIG interface for external DDR3 memory but it is failing to reach timing closure for the reset signal. The reset signal is being generated externally using a 50MHz clock and then synchronised into the memory wrapper logic using a synchroniser chain of flip-flops using the sys_clk of the MIG. WebByte-group (aka byte-lane) is a term from DDR SDRAM interfaces. Although these interfaces can transfer many bits of data in parallel, they are organized into byte-lanes that each transmit 8 bits of data in parallel. Each byte-lane has its own control signals and strobe/clock, which causes the byte-lane to have up to 13 lines.
