Altera devices have fast I/O pins with fall times as low as 1 ns to 3 ns. Because a fast slew rate can contribute to noise generation, signal reflection, crosstalk, and ground bounce, designs must: ■ ■ ■ ■ ■ ■ Filter and evenly distribute power to all devices to reduce noise Use the recommended routing techniques for signals, including clock and differential signals Match impedance and evaluate termination schemes Terminate signal and transmission lines to diminish signal reflection Minimize cross-talk between parallel traces Reduce the effects of ground bounce Power Fil……
