Introduction
The Cyclone
®
field programmable gate array family is based on a 1.5-V,
0.13-μm, all-layer copper SRAM process, with densities up to 20,060 logic
elements (LEs) and up to 288 Kbits of RAM. With features like phase-
locked loops (PLLs) for clocking and a dedicated double data rate (DDR)
interface to meet DDR SDRAM and fast cycle RAM (FCRAM) memory
requirements, Cyclone devices are a cost-effective solution for data-path
applications. Cyclone devices support various I/O standards, including
LVDS at data rates up to 640 megabits per second (Mbps), and 66- and
33-MHz, 64- and 32-bit peripheral component interconnect (PCI), for
interfacing with and supporting ASSP and ASIC devices. Altera also
offers new low-cost serial configuration devices to configure Cyclone
devices.

Vertical migration means you can migrate a design from one device to
another that has the same dedicated pins, JTAG pins, and power pins, and
are subsets or supersets for a given package across device densities. The
largest density in any package has the highest number of power pins; you
must use the layout for the largest planned density in a package to
provide the necessary power pins for migration.
For I/O pin migration across densities, 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 can be migrated. The Quartus
®
II
software can automatically cross-reference and place all pins for you
when given a device migration list. If one device has power or ground
pins, but these same pins are user I/O on a different device that is in the
migration path,the Quartus II software ensures the pins are not used as
user I/O in the Quartus II software. Ensure that these pins are connected
to the appropriate plane on the board. The Quartus II software reserves
I/O pins as power pins as necessary for layout with the larger densities
in the same package having more power pins.
