其中一个问题是芯片太“过于智能”了——与普通芯片的数字脉冲输出不同，它的输出是模拟信号，因此用于数字芯片的测试程序被它干扰了。

Part of the problem is that the chip is just too intelligent - rather than a standard digital pulse it produces an analogue output that flummoxes the standard software used to test chips.

随着系统集成度和应用需求的增加，越来越多的数字模块和模拟模块内嵌在同一芯片中。

With the increase of system integration and application demands, more and more digital and analog modules are embedded in a single chip.

接着，分别介绍了模拟通道部分、数字取样模块、FPGA逻辑控制模块及数模转换模块，包括它们的芯片选择、实现方法和注意事项等。

Then, the thesis discussed the proceeding of the simulating channel part, digitally sampling module, FPGA logically controlled module and AD/DA module, including their chips, realization and notice.
