When using Cyclone® V DDR3 EMIF (External Memory Interface) IP, is it possible to check the value set in the mode register (MR0-3) at the start of user mode in simulation or on the actual device?

When using Cyclone® V DDR3 EMIF (External Memory Interface) IP, is it possible to check the value set in the mode register (MR0-3) at the start of user mode in simulation or on the actual device?

  • Updated

Please note that due to the IP/Device configuration, it is not possible to check this value with the Signal Tap in actual device operation.

In simulation, it can be seen as the value of the address signal (=set value) at the time of the MRS command just before the end of calibration (->start of user mode).
In ModelSim® simulation of Example Design, it is included in the information displayed in the Transcript window.
" MRS Command - MRS [ 0 ] -> 231 ". (The setting 231 looks like a decimal number, but it is a hexadecimal number.)
