Upgrade from EP3C10F256 to EP3C25F256

Hi all............

In my system i am using EP3C10F256, but in future i may require more LEs so is it possible to replace EP3C10F256 with EP3C25F256. I don't want to change my board design so is it possible to use same footprint for upgrade as both the FPGAs are 256 FBGA package.please tell me how this can done, issues i have to consider or suggest any documents which will help me.

    you need to setup quartus for migration devices.

    open your project, menue Assignments -> Device

    Category Device

    There is a button "Migration Devices.."

    just add all those devices you plan to be able to be placed on your target

    Quartus will show only those devices that you can use.

    But pay attention, that quartus will compile for the device you have selected and not for all those on your list.

    quartus know knows about the pins and conditions. if you try to use a pin that is not available on one of your devices, quartus will tell you that.

    so under these conditions you can perform your pin assignments

    if you swap from one device to another on your migration list, you select the desired device with menue Assignments -> Device and need to create the migration list again (maybe somebody knows a better way for that by using some kind of revision)
