PS freeze when memory access from MIG fail

Hello, 

I encounter a problem with a design based on Zynq and MIG controlling DDR3.

 

The normal behaviour of my tester is doing well : calibration of the MIG and access to DDR3 is ok.

But if i unpower the DDR3 after MIG calibration, and try to access to the memory, all my PS freezes.

Do you know if i can handle an AXI timout to make my design mort robust?

 

Regards

Hi watari,

Are you talking about Zynq SoC's private watchdog ?
I was thinking about the possibility of devolpping an additionnal IP to handle memory accesses in case of MIG or AXI bus crash.

Thank you
