Spartan 3E Xilinx入门板是否可以产生1.8V输出？

输出电平由施加到I / O单元的电压电平定义。
如果Spartan-3E板上的VCCO不是1.8V，则不会得到0-1.8V输出信号，而是获得0-VCCO输出信号（LVDS是此规则的一个例外）。
为了改变这种情况，您必须更换Spartan-3E板上的VCCO电源。

以下为原文

The output level is defined by the voltage level that is applied to the I/O cells.  If the VCCO on the Spartan-3E board is not 1.8V then you will not get a 0-1.8V output signal and instead you will get 0-VCCO output signal (LVDS is an exception to this rule). 
 
In order to change this you would have to change the VCCO power supply on the Spartan-3E board.

嗨，
检查原理图我没有看到任何1.8V VCCO连接到任何组。
没有一个电压调节器输出1.8V电平信号-http：//www.xilinx.com/support/documentation/boards_and_kits/S3E_Starter_Schematic.pdf。
检查第5页

Hi,
 
Checking the schematics i do not see any 1.8V VCCO connected to any of the banks. None of the voltage regulators output a 1.8V level signals - http://www.xilinx.com/support/documentation/boards_and_kits/S3E_Starter_Schematic.pdf. Check Pg 5
Thanks,
Anirudh
