Bug fix for Quartus 13 .0 or 13.0 sp1 that fixes OR gates acting like AND gates and AND gates acting like OR gates

HI, Im using a RioRand and discovered that when I OR 2 signals either in VHDL or schematic they act like an AND gate and ANDing 2 signals acts like an OR gate. IS there a fix for this?

Hi Anand, The input pins are pins 51 and 52 on the board for input and 143 for output to led.

How are you able to tell that by looking at the schematic? I don't see anything too me that indicates active low. Just curious for future reference. I don't see tilde's or bubles to indicate a low

I'm not using the on board push button or the onboard LEDs. Using external LED and buttons
