initializing M-RAM

Q's MegaWiz does not let me setup a MIF or a HEX for a M-RAM. I would like to let this device come up with a predifined pattern in the RAMs. (never changes). Ist there a way to do this tho...

I get the same problem. Can you try this way:

use an extern eeprom, say 24c32, depending on your size. store your data in the eeprom.

implemente a I2C interface and related read logic in your fpga.

whenever your fpga reset, it can read data from eeprom and init your ram.

You may need a init_done signal to let other logic know when to start their operation.
