SEAM-300连接器上VCCIO电压是多少伏?
VCC3V3是给子板供电的吗?
供电能力是多少?

LS上有外扩的3路电源(5V,3.3V,1.8V)对外供的电流是多少?

还有:
​1) PRSNT、SCL、SDA、GA0等是否接到FPGA pin了?
2)RESERVED 1-12是否接到FPGA pin了?

3)VU440的ATX_12V 、300pin connector上VCC3V3、 VCCIO 这三组power上下电的timing

1)VCCIO电压是多少伏?
等于连接器配置的电压。最高1.8V。

2)VCC3V3是给子板供电的吗?供电能力是多少?
是。VCCIO 和VCC3V3的最大供电电流都为1A(3个pin总共,事实上3个pin接在一起).

3) PRSNT、SCL、SDA、GA0等是否接到FPGA pin了?

没有接到FPGA PIN。 PRSNT是一个输入信号,要求是L。 SCL SDA GA0用于在子板上安装EEPROM使用。

4)RESERVED 1-12是否接到FPGA pin了?

RESERVEDpin都是悬空的

5)上电:12V->VCC3V3->VCCIO;下电:同时下电。
