【应用笔记】在Quartus II软件中实现Stratix III可编程I/O延时设置(Implementing Stratix III Programmable I/O Delay Settings in the Quartus II Software)
Altera公司的Stratix III系列器件具有一种灵活多变的I/O结构。在Stratix III器件的I/O所包含的不同功能对你系统中的信号相位差管理是可选择的。Stratix III的I/O的结构中，具有不同的物理可编程延时单元。使用选项设置来对这些延时单元进行编程，提供了一种信号相位差管理的一种方法。
Altera® Stratix® III series devices have a very versatile I/O architecture.
Included in the various features of the Stratix III I/O are options for skew
management in your systems. The Stratix III I/O has various physical
programmable delay elements in its architecture. Using the option to
program these delay elements with different settings provides a method
for skew management.an474.pdf
