Simulink Xilinx-Toolbox "XNOR"

[Roger10]

Hello!

I've a problem with the Simulink Xilinx Toolbox with the "XNOR"-Box. This Box is always negate the signal. Is it only a simulation problem or negate the XNOR really the signal?

XNOR should be low if and only if one and only one input is high, so if all other inputs are low, it would behave like a NOT.

The XNOR was working right, that wasn't the problem. The signal was low and high, but it was -1 & 0. But I recentlty found the problem. The input was a unsigned and not a boolen signal! Now its working right.
Anyway, thanks for help!
