AR# 40453 MIG 7 Series v1.1 - Can clk_ref_i, sys_rst, and status signals be located in memory banks (Data or Address/Control banks)?


In MIG 7 Series v1.1, the bank selection algorithm forces users to assign the ref clock (clk_ref_i), sys_rst, and status signals (calib_complete and error) to non-memory banks.

Is this required, or can these signals be assigned to a memory bank (Data or Address/Control bank) if free pins are available?


If free pins are available, it is possible to place clk_ref_p and clk_ref_n in a memory bank, but the status signals are not allowed. However, if these signals are combined in a memory bank, compatible I/O standards are required.

Starting in the 13.2 software release, MIG allows system clock pins in memory banks, but there are no plans to allow status pins.
