1.1.1.6.3. .mif File Format

The .mif file stores the commands that you want to send to the Altera PLL Reconfig IP core. .mif streaming then simulates the commands the user logic would otherwise send to the Altera PLL Reconfig IP core. These commands are address-data pairs in the .mif file specifying the setting to be reconfigured to the new value. Addresses are stored as operation codes (opcodes) in the lower six bits of each entry word.
