Selectable I/O Standards in Cyclone II Devices
software makes it easy to use these I/O standards in Cyclone II device
designs. After design compilation, the software also provides clear, visual
representations of pads and pins and the selected I/O standards. Taking
advantage of the support of these I/O standards in Cyclone II devices
allows you to lower your design costs without compromising design
flexibility or complexity.
