Introduction
Vertical migration means that you can migrate to devices whose
dedicated pins, configuration pins, and power pins are the same for a
given package across device densities.
1
When moving from one density to a larger density, I/O pins are
often lost because of the greater number of power and ground
pins required to support the additional logic within the larger
device. For I/O pin migration across densities, you must cross
reference the available I/O pins using the device pin-outs for all
planned densities of a given package type to identify which I/O
pins are migratable.
To ensure that your board layout supports migratable densities within
one package offering, enable the applicable vertical migration path
within the Quartus II software (go to Assignments menu, then Device,
then click the Migration Devices button). After compilation, check the
information messages for a full list of I/O, DQ, LVDS, and other pins that
are not available because of the selected migration path. Table 1–3 lists the
Cyclone II device package offerings and shows the total number of
non-migratable I/O pins when migrating from one density device to a
larger density device.

Notes to Table 1–3:
(1)
Vertical migration between the EP2C5F256 to the EP2C15AF256 and the EP2C5F256 to the EP2C20F256 devices is
not supported.
(2)
When migrating from the EP2C20F484 device to the EP2C50F484 device, a total of 39 I/O pins are non-migratable.
(3)
When migrating from the EP2C35F672 device to the EP2C70F672 device, a total of 56 I/O pins are non-migratable.
(4)
In addition to the one non-migratable I/O pin, there are 34 DQ pins that are non-migratable.
(5)
The pinouts of 484 FBGA and 484 UBGA are the same.
