Version Found: MIG 7 Series v2.0 Rev 2
Version Resolved: See (Xilinx Answer 54025)
XSIM simulations using the MIG provided xsim_run.sh/.bat fail becase the rtl files such as example_top.v/vhd, sim_tb_top.v and memory models are being referred from different locations.
The xsim_run script files will be updated at a later date with the appropriate paths. Until then, simulation using XSIM should be completed through the Vivado tool and not standalone.
