Hello,

For PLL reconfiguration using mif , you may want to refer to AN454. I attached here for your usage. Figure 7 on page 12 of AN454 might have explanation on how you can put the mifs into each RAMs and call the mifs when you want to perform PLL reconfig.

I also attached Stratix IV design example, it might be old ref design, but it will give you an idea on how to do the PLL reconfig from multiple mifs.

regards,
