PSoC原理图怎么简化？

你好，
我对使用PSoC 3S感到沮丧的是，它们似乎需要大量的电容器和复杂的电源连接。对于非常空间受限的应用，这些可能会使事情变得困难。QFN48封装显然需要9个电容器，10个电源和7个GND连接！
我的问题是：每个电源连接真的有必要吗？每个电容器真的有必要吗？
例如，如果我只使用象限中的引脚作为模拟输入，需要VDdiO3上的电容器吗？事实上，我甚至需要电源连接吗？我可以只使用一个电容器用于所有的VDDIO管脚吗？
在附加的图像上，您可以看到我的空间受限的PCB，以及它的部分示意图。在原理图上，我从两个VDIO0管脚（13和24）中取出电容器，试图给我一些空间。

  Hi,
     
    One thing I'm finding frustrating about using the PSoC 3s is that they seem to require a huge number number of capacitors and complex power connections.  For very space constrained applications, these can make things difficult. The QFN48 package apparently needs 9 capacitors, 10 power and 7 GND connections !
     
    My question are: Is every power connection really necessary?  Is every capacitor really necessary?
     
    For example, do I need the capacitor on Vddio3 if I am only going to be using the pins in that quadrant as analog inputs?  In fact, do I even need the power connection there? Could I just use one capacitor for all of the Vddio pins?
     
    On the attached image, you can see my space constrained PCB, and part of the schematic for it. On the schematic, I have removed the capacitors from two of the Vddio0 pins (13 & 24) to try to give me some space.
