请问是否有可能再制作一个额外的调节板来为斯巴达提供动力？

该套件的原理图仍应在线。
你可以开始更换零件
认为你可能会修理电路板，但过电压很可能超过了监管机构
并且还炒其他薯条。
如果是我，我会尝试更换监管机构，如果是的话
没有解决它，废弃董事会。
如果您不方便更换QFN封装，您可以使用外部电源
产生所有所需的电压并将其连接到调节器周围的跳线上
（每个电源都有一个直插式跳线）。
带注释的示意图在表5中显示了这些：
1.2V FPGA内核（开关）
3.3V FPGA I / O（开关）
3.3V FPGA Aux（线性）
1.8V USB / JTAG（线性）
0.9V DDR2 Vtt（切换）
1.8V DDR2（开关）
3.3V DAC参考（线性）
0.9V DDR2 Vref（线性）
您可能会尝试仅为前三种耗材供电，看看您是否从中获得了生命
在进行任何进一步的手术之前。

哎呀，我刚注意到你说Spartan 3AN而不是Spartan 3A。
abover评论是
基于Spartan 3A套件。
你的无疑会有所不同，但无论如何你应该挖掘
电路板原理图，看看它是否具有相同的电源功能。

以下为原文

The schematics for that kit should still be on line.  You could start replacing parts if you
think you might fix the board, but it is quite likely that the overvoltage got past the regulators
and fried other chips as well.  If it were me, I'd try to just replace the regulators, and if that
didn't fix it, scrap the board.
 
If you're not comfortable replacing the QFN packages, you could have an external supply that
generates all of the required voltages and attach it to the jumpers that surround the regulators
(every supply has an in-line jumper).  The annotated schematic shows these on sheet 5:
 
1.2V FPGA core(switching)
3.3V FPGA I/O (switching)
3.3V FPGA Aux (linear)
1.8V USB/JTAG (linear)
0.9V DDR2 Vtt (switching)
1.8V DDR2 (switching)
3.3V DAC reference (linear)
0.9V DDR2 Vref (linear)
 
You might try powering just the top three supplies to see if you get any life out of the
board before doing any further surgery.
 
[Edit]
Oops, I just noticed you said Spartan 3AN and not Spartan 3A.  The abover remarks were
based on the Spartan 3A kit.  Yours will no doubt be different, but in any case you should dig up
the board schematics and see if it has the same power features.
