Resolved issues:

Known Issues / Limitations:

13.3 - Changes in tool interface files (.mpd)

13.3 - Changes in tool interface files (.pao)

• Common AXI files renamed to avoid name space collisions with axi_interconnect in non-EDK environments.

13.3 - Changes in Tcl script files associated with core (.tcl)

• [<CR618769>] UCF parsing updated to fix the warning message:
  ****** Unhandled UCF line: INST "memc?_wrapper_inst/mcb_ui_top_inst/mcb_raw_wrapper_inst/gen_term_calib.mcb_soft_calibration_top_inst/mcb_soft_calibration_inst/DONE_SOFTANDHARD_CAL*" TIG;

13.2 - Changes in VHDL/Verilog/Netlist sources (.vhd, .v, .ngc, .edn)

New Features:

• Updated S6 MIG PHYs and GUI to MIG release version 3.8.

• See MIG version 3.8 release notes and documentation for more information about changes to MIG, supported FPGA devices, supported memory components, and board design information.

Resolved issues:

• [<CR602184>] Default value of parameter C_SIMULATION changed to TRUE. Parameter value is overwritten during platgen to a value of FALSE. This ensures that the optimal value of TRUE is used for simulation and that the required value of FALSE is set for synthesis.
