* The second area empolys techniques that are quite
different from those of conventional hardware design and
also require a substantial investment in special test
equipment for efficient development and debugging.
第二个领域使用的技术与不传统硬件设计有较大的不同,
为了有效的开发和调试也需要在一些特殊测试装备大量
投入。
* It does not mean that the device can operate
properly at that speed.
那就意味着器件不能在那样的速度下恰当的工作

* It is essential in digital circuits that signal edges
occur in a known order.
在数字电路中信号边缘的已知顺序发生是至关重要的。
* If speed is not required, the Low Power class is a
good choice, not only because of low power consumption,
but because its low speed makes it insensitive to many
high-frequency spikes and glitches.
如果不考虑速度,低功耗好类是个好的选择,不仅仅
是因为低功耗,而且它的低速度使得它对很多高频率尖
脉冲和短时脉冲不敏感
