What exactly are you trying to simulate? Are you trying to simulate the DDR on microzed that is located in the PS? Or are you trying to simulate some external DDR in the PL?
Thanks for the answer
I am tring to simulate DDR located in PL. Digital simulation with Vivado simulator.
I'm still a bit confused as to what you are asking. If you are adding a MIG controller in PL to connect to some DDR3 SDRAM that you have placed on a custom carrier, then I suggest you use the MIG and DDR3 vendor models for your simulation.
This forum response over at Xilinx may be helpful:
If you are creating some sort of DDR structure inside the PL and not a memory controller to an external memory, then you will have to tell us more about what you are doing.
